Video fails to address the nuance: for metal-to-metal contact situations (that aren't very high voltage/heat), dielectric grease is ok as the metal-to-metal phenomenon is preserved. That's how it is designed to be used. Spark plugs on the other hand operate by arcing through a gap - you don't want to alter the dielectric constant of the arcing gap from what it was designed for. Happy wrenching all.
Most just need to know how to implement, now why it works. But good info nonetheless for people who do.
Exactly! Inside "weather proof" plugs, in the studs and terminals in junction boxes, in adverse conditions, such as ground wires on equipment around 🐂💩, salt fertilizer.. just a little at the stud and terminal sealed with liquid electric tape. Rather than things failing in a few weeks, as they do from the factory.. they're trouble free for many years.
Not that anyone is actually going to use it on the gap of a spark plug where the high voltage spark actually occurs.
And, to ensure the high voltage spark gets to the plug gap with the lowest resistance path, you certainly dont want dielectric grease on the nipple of the plug, or inside the boot on the spring/wire connector for the plug.
Another thing, dielectric grease is mostly silicone, so it can actually handle extremely high temperatures👍
Nice explination and i agree video didn't address much of anything @Tedjohansen6535
A small amount inside the boot touching the Coil spring Is not going to hurt anything Silicon grease is extreme high temp its used for insulation as well as liberates rubber to stock it from sticking can also be used in fuse boxes electrical panels and even in Electrical plugs
My wife and I use this. Keep it in the nightstand 😎 electrifying
Good one lol
Yeah but didn't that make your wife have more resistance to sex? 🤭
Ok I couldn't wait; sooo how do you get the thickening residue off? Please don't say "91% rubbing alcohol, as usual . ."
Yeah got to keep those plugs from getting stuck 🤭
Is that you and her in this video?
Great video! Nice to have accurate info regarding a commonly misunderstood product.
You are assuming it’s accurate…
Lmfao Not everything you see is accurate or even Close to Correct
I've been using a q-tip to apply dielectric grease for over 20 years. It made sense to me then, it makes sense to me now.
I always thought it was to keep the boot from seizing on the porcelain so you don’t have to rip plug boots to pieces when removing after using in a hot engine bay.
helps do that also
Highly recommended information. I am from India. After watching your video I bought dielectric grease for my car's spark plug wire. Once again big thanks for such knowledge full making vdo.
You can put it on contact, since the contacts are DESIGNED to make a good physical contact, which is the basis of ALL good electrical connections. Thus, once the good physical contact is made, the dielectric grease will protect against corrosion of the contact and help them maintain a long life of operation. Sometimes you really have to understand what you saying on video before you post it. Oh, yeah, I've been using dielectric grease for 53 years.
You've been doing it incorrectly for 53 years. Nothing he said in the video is incorrect
@@MacAutoDiagonly way to know for sure is scientifically. Two identical, new connectors. Both have same resistance. Add dielectric grease into one of them. Test if resistance changes.
You do want it on the contacts to help with fretting, it seals up the micro pores in the metal and the grease due to low surface tension will be pushed out of where the two contacts actually meet
It makes no difference how much dielectric grease you use. Physics states dielectric grease doesn't conduct electricity but when 2 pieces of metal touch dielectric grease doesn't stop them from conducting in fact the more you put on the less chance of arching you get because arching is electricity through air and since the grease doesn't stop the metal contact at all it would make no difference to put a ton on unless the grease is physically stopping the metal from touching due to suction or compression issues. As long as the metal contact touches you are fine.
THANK YOU!
I that were not true, then ALL electrical connections would not work in air, and jumper cables would not work in the rain!
Underwater welding would be impossible... etc
@@troubleshooter1975 Exactly.
Dielectric grease is non-conductive, and lubricating. I use it on all my electrical connections where moisture can be an issue. My ethernet cameras all get a bit where the contacts meet and where the plug set into the socket. Just a little goes a long way, don't paint it.
I have seen people slather that dielectric grease on contacts like they are siliconing a bathroom shower.
Thanks for showing us how it is done . . . right.
This video is “spark plug specific”. On most other electrical connections it’s important to use enough dielectric paste in order to keep out contaminants.
I lick my finger and smooth it out on my plug threads
So for an o2 sensor connection clip, would you say slather that baby, or keep er on the seal only?
@@rickybobby6409 slather
Proper way for spark plugs..
But you forgot all about what it was originally made for....
Electrical connections, to keep them from corroding.
Most modern truck lights come from the factory with dielectric grease already in the contacts.
Good video though!!
A little bit of grease on the contact is fine. On hard to reach plugs, that's saved me from having the boot tear away from the wire numerous times! It's a solid connection with metal to metal contact, so you're not effecting the current flow unless it had to arc to the contact. Obviously you don't want to excessively load the inside of the boot (and not be able to press it on) but a little coating on the ceramic and contact is fine.
Mind that in a modern engine with the hard plastic boot, it's not really necessary to coat the contact for easier removal. My case usage is the simple plug wires scenario. Where a stuck (or tight) contact ends up with me ripping the entire boot away.
I use dielectric grease daily on Honda ground points , couplers and battery terminals .. On couplers you put the dielectric grease in the female mini pins , NOT the coupler end with the male pins because this will cause the coupler to hydraulic (push apart) when plugged together ..
I use it in my atv's electrical connectors. It keeps out water, moisture and dirt which prevents corrosion of the metal pins or contact points in the plug, this also makes the connector easier to take back apart when needed for service or repairs later on. Im my experience it keeps electrical connector plugs in better condition longer than not using dielectric grease. Keep in mind that in my area, an atv can be regularly submerged in water when crossing deep streams or wetland areas with deep mud.
liquid lectric tape stays flexible
@@joe8397Dielectric grease stays as grease, so it also stays flexible, forever...liquid electrical tape becomes progressively harder and harder over a period of time👍
If it didn't work the original way shown, how are the millions of vehicles done that way working without issue
Isn't dialectic grease also good for using inside electrical pull-a-part connectors on cars, to prevent the metal contacts inside from corroding?
There is at least one place on the airplanes where the maintenance manual calls out to fill the connector with dielectric grease before insertion. That is on prox switches that are exposed to the elements.
@@rael5469
Thanks!
Yes, it's good to use on the rubber weather pack seals or inside the female half of plug together connectors on cars, it helps the female connector housing/rubber seals slip together easily and avoids the rubber getting stuck/damaged, and also repels moisture to keep the connectors water resistant, but shouldn't be used on the electrical pins as it can cause poor electrical connections👍
You can use it on the surface of the boot itself as well. From experience, it helps the boot survive over time a bit better, and helps insulate any spark permeation through the boot itself when wet. We used to use it on the plug wires on our mud bog trucks and off road vehicles that tended to see a lot of deep water.
Gitchu some 303 protectant!
Rubbers like to stay wet.
I disagree that it's not meant for contacts. It most definitely IS designed for contacts. The enemy of electrical contacts is oxidation. Many people think that solder makes electrical connections. It does not. It keeps electrical components in contact with each other while preventing oxidation. Dielectric grease does the same. Where the contacts actually touch, the grease will be pushed away, while protecting the rest of the contact area from oxidation. I'm an electrical engineer.
Now the point in the video that you shouldn't coat everything with it, IS valid. That will just attract dirt.
Thanks, very good to know that.
Yes you are right !
The opposite stuff is called conductive grease, which keeps electricity flowing thru rotating/sliding points that would wear down if not lubed somehow. (Putting conductive grease on the center contact of a distibutor rotor seems like a good idea but don't do it! Wearing out a cheap distributor rotor every year or two is preferable to finding and removing tiny amounts of excess conductive grease that flew everywhere inside the cap, where it can conduct the spark to ground after Homer applies a big gob of it there.)
I did not know that there was such a thing as conductive grease. I do suspect that it's use should be limited to very specific applications where spread of it will not provide some kind of a shorting.
@@davegaetano7118 Conductive grease is used for keeping electrical path to ground for copier/laser printer drums which are dissipating a charge from “white” areas as they rotate. Specific enough?
Interesting. I also never heard of conductive grease. Sounds perfect for battery terminals.
wow thats a true fact, do not put dielectric grease in the end of a coil pack boot, it will prevent electricity from the coil to the spark plug. I found this out first hand today on my 2009 Ford Expidition 5.4.
Going the comments makes it clear that there's no general agreement on dielectric grease at all.
There doesn't need to be. As the NEC always says, "The manufacturer calls the shots"
We had new pieces of heavy equipment that had a problem with the taillight back feeding electricity to the dashboard of the machine. We traced it down to the harness connections and the bulb socket being over stuffed with a grease. Removed the grease and the problem went away. We did not test the grease to see if it was dialect grease or if it was contaminated with a chemical conductor like salt from the overseas shipping of the equipment. It could be that the quantity of grease used kept the sealing gaskets on the connections from creating a tight seal on them. I still use dialect grease but very sparely a thin film is all that you need.
I had that happen with a connector going to the computer on some equipment. It was causing all kids of weird symptoms. Cleaned out the grease with brake clean and shop air. Put just a little around the gasket. All electrical problems went away.
Dielectric grease is not conductive. That's all you need to know.
The mechanic I work with turned me on to using dielectric grease in place of anti seize. Needless to say we use that s*it on everything! Works great!
Good stuff....just keep it out of the paint booth. Good body shops won't let silicone on the premises.
Wow. I just watched another video that claimed the exact opposite- which is to say that it should be put in the electrical connections to help conduct the electricity all the while protecting from corrosion.
Thanks for your comment. Our main focus is to educate on the fact that the primary use of the application is to seal the electric components to keep out dust and debris. This is the statement from Permatex the makers of the Dielectric grease we are using: "Dielectric grease is non-conductive. It should be used in and around the boots and on the ceramic part of the spark plugs to prevent sticking and corrosion, and of course moisture. It should not be globbed into the connection point, though a small layer won’t do harm. For maximum spark though it’s probably best to use it as a barrier to moisture getting into the boot, but not on the connection point itself."
Yeah, it's so funny how ignorant people are. Even professionals? Lol
Dielectric grease when used properly, even on metal to metal contacts, does not have any significant effect on voltage, amperage, or resistance. Additionally, when used on metal to metal contacts, it will not "improve" electrical conductivity either as it is an insulator. Its purpose is as stated, corrosion resistance/prevention.
ua-cam.com/video/GNiEJfgS8cE/v-deo.html
That's a link to the manufacturer of the dielectric grease telling you to basically fill the spark plug and coil boots full of grease and then push them on.
@@notacreativehandle Def. not what I experienced (re: "No significant effect on voltage, amperage, or resistance.) . . I used it on all metal surfaces as you say and even what the (vague) instructions said on little pkg. of it I bought, and immediately started having all these issues and codes I'd never had before . . one of which was a dead-giveaway: "C1109-00 ABS Module reading low voltage" (and I have a brand new battery).
Grabbed a bottle of 91% rubbing alcohol and clean rag and went to work. All codes went away . . Ran my experiences by the owner I know of a big high-end shop that builds cars for ppl in Dubai and has many degrees and was high-level mgmt. on Toyota assy. line for years; his answer concurred: "Correct - should not put it between surfaces".
On some high-current things you might get away with it, for example I could still *start* my car fine (although a little more sluggish) . . But it most-def. created many codes and issues pertaining to sensitive electronic monitoring systems . . even made the MAF readings go bonkers for no other reasons, even though I *only* applied it to the battery posts/terminals/connections (!) And now, with NO dielectric grease on (and in-between) the same connections, I have NO codes. Now will apply said grease to *outside exposed metal surfaces AFTER re-assy.* as it's intended (vague instructions on pkg. leave a LOT to be desired . . )
Despite the fact it has "electric" right there in the name, it's a fairly common misconception that dielectric grease is capable of conducting electricity. In actual fact, dielectric grease is an insulator and doesn't conduct electricity
This guy still has the same jar he bought in 1980😂
Well, I’m 70 years old and I’ve always applied die electric grease directly on the contacts to prevent corrosion. It’s always worked great and it’s always made good electrical contact between 12V plugs and receptacles on my trucks and trailers. I’ve also used it on battery terminals to prevent acid build up and used it on the top of spark plugs as well. When GM came out with the HEI electronic ignitions they pointed out to use it on contact connections of spark plugs to prevent them from burning out due to the high voltage of the new electronic ignitions at the time. So if I’ve been doing it wrong all these years, I’m going to keep on doing it because it’s always worked great for me.
I have argued at a local Autozone with the manager that dielectric grease is used to stop the flow of electricity, and not to aid it. The prefix "dia" means "against" in Latin, if not mistaken. (PS: I was thinking about trying to get a job at that Autozone, but realized after arguing with that manager, that I wouldn't be hired; the manager in question actually got pretty hot under the collar over the conversation, since they really push the sale of dielectric grease to actually "aid" the flow of electricity in "all" electrical automotive connections.)
And you were wrong. Dielectric grease is nothing more than silicon grease. It makes good contact points stay good. I know folks that use it by the gallon.
@@rodneymiller5926 Did you watch this video?
@@schwinn434 yes i did
Except a phenomenon occurs where silicone paste is both an insulator and aids conductivity by filling the microscopic pores of the metals and creates a better connection above 1 volt. Below 1 volt, it MAY impede some flow of electrons on low amperage millivolt systems. You have to remember how electrons flow and that they don’t flow in an air gap situation as well as they do in a non air gap connection. The electrons are traveling at 2200km/s until they hit resistance and slow which creates heat. Any reduction of them slowing keeps the system more efficient. Dielectric grease is an insulator, but in an electrical connection there are imperfections of the metals contacting each other ( like an automotive plug pins - socket ) and you don’t want electricity jumping across air as that causes pitting on a microscopic level ( and eventually as visible corrosion and reduces the overall efficiency of the connection. The dielectric fills those imperfections so the current flows ( not through air ) in nice metal to metal contact. Where the metal to metal contact doesn’t exist, the silicone paste prevents an air gap jump. Test over and over have proven that Dielectric silicon grease on a connection does not in any way reduce the electrical flow. It does however prevent any intrusion of moisture or contamination that can and will cause corrosion and a loss of efficiency of the electrical connector. Unless you plug a connector together in a dry vacuum, there is moisture which is displaced by the application of waterproof silicone grass. Almost every car tech service manual, TSB and recalls involving electrical components says to check for physical damage to wires and connectors, clean terminals and apply a light coating of dielectric grease to the terminals during re-assembly.
Well I use it on my 30A 125 V motor home conection the plug stays cool and there is no sign of electrolysis.PS I use a healthy coating directly on the metal contacts
Great explanation and easily understood. Thanks guys! I was thinking about using dielectric grease to insulate my outdoor video surveillance camera connections. The heat shrink tubing alone just wasn't up to the task. Living on a barrier island there's a lot of salt water spray that creeps into the connectors under the tubing so I will give them a coating before sealing them again. Your explanation provided the info I needed. I hope it works on the BNC connectors. It sounds ideal for the DC power connectors.
I wrapped my BNC and power cable connections with electrical tape to keep them together, that may work for corrosion too.
use liquid lettric tape in a bottle seals out the elements and stays flexible
"Thanks guys! I was thinking about using dielectric grease to insulate my outdoor video surveillance camera connections."
Conductive grease will also seal your connections as well or better. I used to have trouble with my trailer connections until I cleaned all the copper contacts and put conductive grease on them. No more problems and nothing shorted out.
Get yourself a small roll of “Denso” tape as extra insurance to wrap your final connections with-It is salt water/weather resistant and is easy to use and will serve you well!
Thank You. Living on a barrier island we get pummeled by salt spray and heavy winds several times every winter and summer through fall is the occasional hurricane. The tape sounds ideal, just ordered a roll. Thanks again.@@FIGGY65
Dielectric grease also helps remove heat and seals water away. That is why it is used on bulbs to keep their contacts dry and keep the heat from the bulb from burning the bulbs connector.
Keeping the contacts from oxidizing eliminates extra resistance, which is the cause of excess heat.
Damn no wonder my pops old buick would melt his 3057's like they were goi g out of style.
How does it remove heat?
Excess heat is caused by the oxidation of the contacts, creating extra resistance in the circuit. The dielectric grease helps to prevent this oxidation from occurring in the first place. Hope this helps to answer your question.@@Spiritof_76
Your thinking thermal paste,
@ min 0:52 I see the configuration of the assembly inside the boot: coil spring. NOW I AM BELIEVER NO DIELECTRIC GRECE (D.G.) ON SPARKPLUG METAL TERMINAL.(YOU MAY NOT BE ABLE TO PUSH OUT THE D.G. COMPLETELY BETWEEN METAL CONTACT).
Thank you for the video!
Very useful for all the rubber trim on your car. Apply sparingly and with your finger in a very thin coat and use a micro fiber towel to remove the excess. Lasts a long time. Much less expensive than specialty products for rubber...
Yep, you want a copper, silver or Gold bearing grease to improve conductivety!
Spot on👍
Finally, someone that doesn't just splodge huge gobs of the stuff into the end of the boot thinking they're doing the right thing🤣👍👌
This stuff ain't cheap, so definitely don't want to be wasteful, and potentially using it wrong will only cause more problems.
This is the incorrect way to use dieelectric grease. It's not a conductor so you don't need to worry about where it goes when making to metal electrical contact. You wan the grease to coat every bit of metal to stop corrosion. The areas that make contact will displace the grease. This is why you coat the back of bulbs and your battery terminals liberally. It prevents the metal from corrosion due to the heat and exposure to the elements. WIth spark plugs it helps prevent the arcing except from where the metal is making contact as well as protecting the boot from overheating, drying out and then cracking.
I agree. I think this video is more “spark plug specific“. For most other electrical connections, it’s important to use enough dielectric paste.
The starter solenoid in my 33 year old motorhome had this type product thickly applied to the contact plate and it hardened so hard that I had to scrape it off with a knife because as the plate jostled around sometimes contact was accomplished but usually not. I tried removing the stuff with acetone, gasoline, alcohol, goof-off, mineral-spirits...no effect. That stuff does not transmit electricity. The solenoid was the type that is not attached to the starter but installed remotely.
Maybe we should use this inside chevy 4.3 distributor caps ,,,, There has to be some way to make them last longer.....
Directions on the tube I bought says to lightly coat the porcelain part of the spark plug, and that's all.
back in the 70's my dad would use honey on the battery terminals to keep them from corroding. It worked. I use dielectric grease. it works too!
Sweet 😆
Talking about honey reminds me of when I was around 5-6 years old my dad asked me to get some honey from the house because the belt on the combine, which had a flat belt, was slipping, so he applied some honey, so it gained traction
Then the rats and mice smelt the honey and chewed up all the other wires on the truck.
But the battery terminals didn't corrode
If my dad ever had to deal with chewed up lines he said anything, and i used that method on my first car 1972 camero and no chewed up lines ever till i sold it few years later. dang i miss that car. @@Greg-xv9qj
@@Greg-xv9qj. Oh 💩 but you got that one right. And it’s even worse today with these manufacturers going with these green wire coatings that seem to draw the roads by themselves. I couldn’t imagine the worst thing and put a nice dollop of honey on the end of a connector to call those things in like a beacon.
It's used on brake calipers and drum brake back plates too.
Very good. Funny stuff out there!
I have been telling people this for YEARS.... Its suppose to be placed on the contacts!!
this should be played during the superbowl so everyone can know bc shii I didn't know! thank you!
Actually you can put that stuff all over electrical contacts. Yes its an insulator, but where there is metal to metal contact, it doesnt effect the connection. So its perfect for all automotive electrical connectors, and spark plugs (everywhere but the tip)
Be careful telling this to veteran mechanics with gigantic egos! Ninety percent of mechanics don't realize dielectric grease is an insulator and then proceed to place it all over ecm pins before attaching the harness connector. Yep! I've seen this many times even after explaining it's proper use and function. There's no cure for mechanics or electrical engineers egos. Just ask them! LOL!
Other than wasting product, using a large glob does not hurt anything. A proper connection with proper contact pressure will not be negatively affected by dielectric grease.
True I had been using it ‘wrong’ for so long.
Yes it will.
@@royblackburn1163 How so?
@D Dielectric grease is not conductive that's what Dielectric means it can only make connections worse, it does not get squeezed out or scraped out fully, it can and does reduce metal to metal contact area. In this day and age every decimal of a volt and every ohm counts with modern engine sensors, anything Dielectric can make your car run like a bag of sh*t, make a good clean contact with contact cleaner first then put your grease on second if you're concerned with corrosion is the way to go.
@@royblackburn1163 You said "it does not get squeezed out or scraped out fully, it can and does reduce metal to metal contact area". That is the first I have heard of that issue. Do you have a reference to either a properly controlled test or specific use directions from the manufacturer(s) of dielectric grease?
This was actually very helpful to know
So your saying I should go back and wipe it off all the hundreds of fuse blades, pin plugs and blade plug connections I've used Dielectric grease on because they gonna not work someday? Lol
So they made this stuff for coil overs...... Well i wonder what that stuff was i have been using since i do not wish to say. Listen up kids. Use it inside hoses. Use it on push type plastic connectors. No i do not mean electrical stuff. I mean trim parts and push pins on atvs. And if you are quick and snappy you will figure out how to keep silicone from sticking where you do not want it. Yes that super sweet bead you see around the tub......
so you're saying it will disrupt or weaken the electricity. if you was to use it on the metal connections that touch one another? what about the air that's trapped inside the boot? and if there's air even if it's the error that you trap in between the two electrical connections there's always some sort of moisture humidity? I never knew there was such a big debate about this topic. but I can't find anywhere that shows using dielectric grease on the metal connections makes the electricity that passes through perform badly. I mean that's what you're trying to do is stop moisture from getting to your connections and insulate it not insulate the rubber or plastic that is surrounding the electrical connections. putting the grease on them as well will help stop dirt from getting even close to the connections but covering the surrounding areas and not the connection itself just doesn't make logical sense unless there's some sort of proof where it diminishes the continuity. so why not put it on the connections? I understand it's not going to make it conduct electricity better immediately but preventing corrosion or rust on the metal parts will make it perform better down the road in the sense that it will not start to fail due to corrosion moisture dirt etc.... but you actually have to cover the connections no? that's producing the electricity instead of covering the rubber or properties around the connection. all the certified electricians I spoke with and the companies that actually make dielectric grease state that it's okay and makes more sense to cover the connection so moisture will not and cannot get to that metal . and on the chance that I am repeating myself I apologize but it just seems so obvious to me and I can't get it through my head while somebody would say that is being done wrong maybe being wasteful by using too much. again... it won't improve it but it does not we can or hurt the electrical connection unless you're working with something that non-contact like the other end of the spark plug where is generating electricity between the two connections with an air gap I can understand why you would not want to use it in that situation but metal to metal connections is what this is made for according to the manufacturers of dialectic Grease at least the two that I emailed.
Show us those emails, because there's plenty of those manufacturers right here on UA-cam saying the complete opposite of what you just said lol.
Someone else posted a link to a CRC video where they show from the manufacturer caking it on. Even on the directions of the PermaTex product, it says to fill the sparkplug boot. They sure say it with conviction on this video like they know what they’re talking about. I almost believed them until someone else posted the link above to CRC coating all parts heavily.
To prevent moisture ingress, yes.
To promote electrical conductivity, no.
The definition of Dielectric literally is 'an insulator' ie. prevents electrical conductivity🤣
Dielectric grease keeping my car running. Had a spark plug boot rip trying to remove it. Slathered the rubber where it broke off with grease to seal where it ripped and it's running fine with no misfires. Just did that till I have time to fish out there piece of the boot that ripped off attached to the plug and buy a new set of wires. Working great for temp fix. If you have a spot on your wires where the electricity is arcing through can smear that stuff all over the outside of the wire for a temp fix too.
I use it to pack connectors on my motorbikes to prevent arcing/instability in old connectors,and then it helps waterproof/prevent shorting in plug connectors, yup, then if you heat shrink you have a good chance of that connector remaining reliable fora years to come, not forever it does dry up eventually and needs to be re-cleaned and packed but a lot of older connectors the pin socket style with get worn down, then only make contact say at the tip, well down hear the base of the pin it will arc, thats BAD, where you get lights flickering, needles jumping, engine missing so forth, I find if I pack with dielectric grease they are stable fora few years till I need to repack them..
a lot of connectors by nature will get waterlogged and then create a myriad of issues, shorts, no start scenarios whatever.. cuz they will put a "cover over them thats open on one end, the goofy rubber boot that's too large to do anything, ditch if its in an area that gets soggy when riding in the rain or washing your bike pack with grease, then use heat shrink, at each end of the heat shrink bad a good dollop of grease, to create a waterproof seal so no water can get to that connector/plug joint.. if packed with grease condensation isn't an issue either and it does prevent corrosion so forth . . .
but look this stuff isn't heat resistant, so don't think if you put some on a spark plug boot its going to stay for more than 4 hours of running in hot condition, nope, it dries up . . . if you want to create a small seal like where he put it use a heat resistant grease... mo betta
That's actually not right. Although it is an insulator, when the contacts are brought together, the grease is pushed aside by the pressure of the connection. It's perfectly fine to blob it all over but there's no need to waste it. Unless somebody else is paying for it. Then you can smear it all over your face and go running around the shop screaming. That's always fun.
😂the first part was great. No,no,no that's not right🤣 totally unexpected, great video 👍🏻🙏🏻
Lmfao 😂
YOU GUYS ARE FUNNY AND INFORMITIVE! THANKS!
Very good info and I learned something today, thanks.
Glad it was helpful!
always put dahlectric grease on yer marbles before placing them in mah mouth .... good vidjeo
You could use any silicone based lube to do exactly the same thing. TBH its more of a gimmick to get you to buy it.
Die Electric is in the name , does not pass electricity, for an easy way to remember
If you seen his hands shaking..
I did this years ago on a truck i had just changed the coils on thing wouldnt even run at all lol you lice and learn so i had to take em all back off clean it off ran fine after that lol
literally everyone ive asked how to use it says to do it like that first example. whats scary is the manager at the autozone said "its dielectric, so it allows current to flow" and i was like "i have it on good authority that thats not what that means"
There is a conductive -dielectric- grease that is black,might have carbon or graphite in it,I think you have to be careful not to create a short circuit with it.
Seems to work on Maglite tailcap threads.
I made a mistake in calling it "dielectric",it is "GC Conductive Grease and Anti-Oxidant" "Lubricates" "Dissipates static electricity" "Anti-oxidant for electrical connections"
"a mixture of soap type lithium grease with zinc and graphite fillers."
I guess you could possibly create trouble in the form of a short circuit with it by creating a track between + and ground with it. Maybe especially if dealing with high voltages as in AC power?
Maybe a true dielectric silicon grease would be safer as a "bulb grease" or as a light film on automotive electrical connector contact pins?
I think such things as taillight bulbs in sockets and harness connectors to the Jeep taillight assembly tend to get corrosion and high resistance/ intermittent open circuit problems because of heat,air and moisture penetration unless protected with a thin film of some kind of grease like substance when the bulbs are replaced or the connectors are Removed and Replaced
@@davidpowell3347I highly doubt there is such a thing as conductive dielectric grease, more likely it'd simply be called 'conductive' grease.
The name Di-electric says it all.
Di meaning 'resistant to', or 'barrier to', or essentially non-conductive.👍
It is actually an insulator. Dielectric foam on the inside of a cable shields the center conductor from the outside braid of a cable. Cable TV cable is an example. The grease is a paste form of that.
Great job! 22 years as a mechanic and I have been using this stuff all wrong! Thanks guys!
Well maybe
Dumbest comment section ive ever read, but too funny to stop. You should all hear yourselves.
It’s self explanatory in the name of the product
Die electric meaning an insulated grease so no current passes through it
You guys are doing it right. I see so many UA-cam mechanics filling the boot.
The Ol' guy has the best knowledge on youtube!
Exactly right. If you just put a blob on the end of the plug boot, 2 things happen; 1. it will stink like hell untill that shit burns away and 2. when it engine gets hot, your plugs wire will want to push off of the plug because of the gas created by excess dielectric grease expands. Use a cotton swab to smear it around, no big blobs.
I'm sorry, but I couldn't understand a single word you guys said!
Scotty kilmer would disagree with this video completely.
Do NOT use dielectric grease to make your motorcycle tires shine.
Smart Idea 💡 👌 👍
At least not on the parts that touch the road...if you value your life😁
Those that gob it all over also refer to a rounded bolt head as being stripped, think Seafoam is something to use in everything, and jump on every new fad like it's the greatest thing ever only to stop when it's no longer 'cool'.
Take the grits outta your mouths. Speak slower. Articulate.
I wish I had the time to pull out a cotton swab, take the wire boots apart and do all 8 of them and then do the other 8 of the boots going into the distributor. All while the customer is "patiently" waiting for me and no way of having the shop on me for why it's taking so long for doing spark plugs and wires.
If you can't, you can't. A lot of industries have those same type conundrums. That doesn't mean it's right not to.
Is this good for sunroof/moonroof tracks and such
So the guy in the Permatex hat needed a class on a Permatex product?
Can confirm the gob at the end doesn’t work the way you’d want
Truly amazing video. Thank you so much!!
Lost me after 30 seconds....... get to the point and stop the banter...
This guy has no clue. Read the instructions.
Great video , gave me a chuckle! Great fun thanks for the help
Just been lookin into this cause recently a garage went to change my plugs pulled the coil pack off and one corrosion and it snapped my coil pack as the vauxhall corsa is one coil unit it cost me 150 quid for new coil pack
Thanks for the video I've watched a few but you put it not where some was. Thanks from the UK 🇬🇧
Clicking the DO NOT SHOW THIS CHANNEL button 👎
What's the stuff that's placed under the electronic module in the distributor of a small block Chevrolet?
That's heat sink paste. It pulls the heat from the module into the distributor so the module won't cook itself.
Thanks, for us home shop bozos this is good stuff.
You gotta should get video of the year!! Just awesome!
it's staged so the young guy does it backwards and the older man shows and explains what dielectric grease is for and how to do that.
DUH
My electric smoker develops a hotspot where the plug inserts onto the element. What product should I apply to these electrical contacts to provide maximum conductivity?
Thank you for this info! I’m barely competent in wrenching and couldn’t find the specific answer!
B.S. - He is using it as a simple lubricant. The main use of this is to encapsulate the actual connection, preventing moisture/corrosion entrance.
Dude in the gray shirt looks like he has the shakes ?
Bigger the gob the better the job.
i put this on my electrical connectors and now iam having car problems. it says this is only for spark boots or battery terminal, not the connectors.
Facts. I made a terrible mistake of using this the wrong way lol. I use it on soldered joints before covering with shrink tube. It does help keep the joints from corroding. But..... My dumbass covered the contacts on my spark plugs, coil contacts, and the contacts between coil packs and ICM, and I had all kinds of issues. I chased that problem for months on a build I did. I've built engines before, but had never used dielectric grease before. I thought I was doing a great service to the ignition components. Boy was I wrong lol. I was having minor misfire issues at idle, but that was only noticable with scanning equipment. It was when I was doing a pull, it would start breaking up really bad at higher rpm. I couldn't fit the life of me figure out why.
Why I didn't put together "non-conductive" in my head, I couldn't tell you lol. Lessons learned 🤷
@@boosted0079 yeah if you click on thr description of this video it takes you to amazon and you can get a electric conductor grease. i didnt click in the link until later, now i have to buy the electric cleaner to clean it up but the item seems to be out of stock in all the stores i visited and i hope they put it back on stock because i need it and othet people need it too
Teaming Portal 🤣
Hey guys. I agree that silicone grease is great for sealing, but I have to disagree that it shouldn't be used in the connection. It will reduce any corrosion by sealing around the immediate mating surfaces and allowing minimal to no air to contact them, kinda like a flux.
"The bigger the glob the better the job" sure ain't right! A little dab will do.
I remember when I was chasing down the daytime running light problems in my Yukon. The things kept burning out, they got hotter than the flat rock the cow squirts on, and was arcing the contacts. I bent the pins on the bulb out, I actually did fill the connector on this one, and put it back together and I haven't touched either side in about 10years.
