Just wait till China start producing them. These are basically quick connectors that are used in car AC's. I predict you will be able to get them for less then $10.
Unless your gauge is only servicing one refrigerant and you're keeping the gas in the hoses in between connections, you're loosing quite a bit more gas from the system by pressurizing the hoses when you connect them to the system than you are by just attaching the hoses and loosing a little hiss or spritz of liquid, aren't you? Unless you're _really_ slow when you screw the fittings on.

When I was a kid we lived next door to a dairy. (Back when our town still had milkmen.) The father of one of my schoolmates was one of the drivers. He showed me how they recharged the ammonia refrigerant in their trucks by hooking them up to a big tank with a hose with a fitting like that, but bigger.
Lots and lots of units where there's not enough room to fit these due to bad engineering from the manufacturer not thinking about the service techs. Price is too much. Obviously the hoses must still fill up with refrigerant. So there may be less squirts upon connecting and disconnecting, there's still refrigerant loss in the gauges and hoses.
That's why I love the fieldpiece probes and tees and backseat control valves. Incredibly small amount of refrigerant loss when connecting/disconnecting
Not to mention if you leave the hoses pressurized then hang your manifold in the truck on a hot day your gauges could blow a spring with the increased pressure. Don’t ask me how I know.
There have been designs like those before from about 10 years ago. The problem was when disconnecting if the Schrader valve is bad once you release the fitting, you're gonna have the refrigerant spraying out. With the low loss fitting, as your unscrewing it outside of the initial spurt of refrigerant if for some reason, you detect a more constant release, at that moment, you have the potential to realize that the Schrader valve might have stuck. At that moment, in time, he won't be in as bad a position as you would, as if you just detached the quick coupler and had a dead spray of refrigerant coming out into your face . From what I have been able to tell and I am no engineer by any means is that the standard quarter inch connectors tend to be a piece of brass that screws on and pulls a nylon cone against the valve to seal it. The anti-blowback/loss fittings Are basically the same thing except instead of having the nylon cone they use the same thing that those fittings use which is an O-ring to seal when they are tightened.
You're looking at around 3 oz of refrigerant per hose loss every time you connect a manifold set with standard length hoses. Do that enough times and you ARE the leak. Yes, you could disconnect the high-side and pump the gauges down but you're looking at possible contaminants or a non-condensable unless you bled your manifold first. Anytime you open a system to check pressures there is going to be a loss, the idea is to limit that as much as possible. When I got to the point, I needed to check super-heat or sub-cooling I had over the years, built multiple sets consisting of only of high and low side gauges dependent on the equipment connected directly to a low loss access fitting. A simple Cooper electronic thermometer with decent set of clamp-on probes will with those gauges tell you everything you need to know and the refrigerant loss is much less than with a manifold even if it's properly bled and pumped down. Here is where I piss a lot of people off, why did you open that system to install a manifold in the first place? If you've got a good TD, compressor amps are in a narrow range of 80% FLA , you KNOW the coils are clean and airflow correct and there are no odd noises or vibrations what are you looking for? TD will point you toward airflow, capacity or refrigerant, compressor amps will point you to refrigerant, or an electrical/mechanical issue. Unless something is pointing you in that direction why are you opening a system?

I switch my gaskets the moment I see them wear and keep the valve depressor a bit tucked I hardly have any leaking I also don’t use hoses only probes Just an idea for techs out there I’ll go through a pack of seals per season Not too bad. They’re like $10 bucks
You've just been watching youtube videos waiting to find out about new inventions that have been around for 40 years? You need to get the F off your phone bro.... Just walk away
It seems convenient. I would not change over to prevent refrigerant burns. I would do it for the convenience of Not having to twist on and off traditional fittings. It gets tedious after years in the trade
I haven't used gauges in 5 years. Probes are the way to go. Thread the depresser in your tee and you don't lose refrigerant. Cool concept but won't fit in a lit of applications due to size.
Looks like a great product for test ports that are easily accessible and pointing in the right direction. Seems where you would need these the most you wouldn’t have the clearance, Clarence.
Show me how they work in the most common scenario. Make sure it's hot AF outside, have the system running and in the same continuous video frame, show me the loss using the conventional hose connectors and then with these unique adapters. And are the orings unique in size to the adapters, thereby marrying me to this company for a $50 bag of $2.00 orings every few months?
Really? Not once? In the past 35 years I have done it a few times because sometimes you're just dealing with a nightmare of a installation that some got away with and you just do the best you can.
@@July4.1776 oh idk failed core? Literally several reasons besides technician error that can cause it, which is how I know you're full of shit. The fact you are so confident in "never" is how I know you're just a liar dude.
And you'll end up contaminating the refrigerant in the process. The o rings do not ever need to be lubed in this application. If anything, the ONLY safe lube to use would be Nylog.
This is really good thing bro but I still lose some refrigerant left in the hoses. I try to return as much as possible by letting it go through the suction line but still some of it is always left in them. I guess it’s just a diminimus amount and you just can’t avoid it.
Okay so cool idea but that just made me think of an idea... why not just use pressure transducers to read pressures with out a manifold, so no long line set and you just want to see what pressures you're seeing in the system. Maybe make it so the low side has a port to add refrigerant so then you wouldn't need to disconnect anything and no loss at all....
@@diyhvacguy the reason I say this is when I saw how the adapter connects to the hose “dock”, it makes it stick out very far and if anything presses down on it, the thing is gonna snap. I don’t have to connect hoses all day like a lot of techs so this might be great for you, but not for me. I’ll thread my fittings thank you.
25% of the reviews on amazon are 1 star. People are saying the O-ring pops out on the high side when you remove it. I think I'll wait until the price comes down and the reliability goes up.
What about the injection of air? I'm not jumping on you. I'm just curious. How can you bleed out that air that exists within the chamber. I appreciate your time making this video.
I think that the Sealright hoses work great and are a fraction of the price. You lose an extremely minimal amount, if any, refrigerant. I've used these hoses for a couple of years now.
I got burned pretty badly in my first month, having to go to a burn center and be out for like a month almost, but that was before i knew about the two finger method... but there is certain situations where its basically impossible when its in a dumb spot, so this would be good for that but man i hope they dial that price back
Looks like somthing a young kid would waist money on 200 bucks for somthing that will fit maby 60 percent of units I work on might suggest good pair of gloves for 20 bucks
True. There are a lot of units you could get one of these on and not the other. Im about to upgrade and get the job link setup. Those wireless/hoseless ones barely release any refrigerant. But, like these, they just can't be used sometimes.
Those fitting are to large in lots of situation. I used low loss fitting and they worked good. The best solution I found was to use a regular fitting with the hand operated shot off valve about 5 inches back on the hose so the refer loss is hardly nothing
I noticed a lot of people talking about refrigerant still being in the hoses. Do you not know how to easily suck it buck into the system? One of the first things I learned when being taught how to use gauges.
Why? 36 years in the trade, standard low loss fittings for a tenth of that price have served me well. I see no reason to purchase this item, especially at the ridiculous price.
They came and gave us some samples when I used to work at Johnstone. Very cool and high quality product, but too expensive and sometimes impracticable due to the clearance you need to connect. We chose not to stock them and I’ve never seen anyone else with them. My current fieldpiece Joblink probes have the best connectors hands down. They aren’t the giant low loss, minimal and just great quality.
just as recent as last week, r410a cost me $236 per 25lb jug. To think i would spend $200 for each set (straight and 90 degree) of these, is ludicrous to save a couple of squirts of refrigerant(especially, when the EPA said that a small amount of refrigerant loss is acceptable when connect and disconnect hoses). This is for the new techs only. As for seasoned HVAC+R techs, if you have been doing HVAC for a while, you know that there are, at least. three cheaper more effective ways to minimize refrigerant loss, than even the low loss fittings.
Brother I love it, but there’s some units their not going to work on because their so long and the idiot way they designed some of the old units. I love it though and would buy it.
You would think with the under the EPA’s standard minimum refrigerant loss that these type of connectors would be standardized and way ahead of their time. Usually a great deal of refrigerant is lost in tight areas in struggling to get on and off especially high side.
What lube can be used on O Ring to keep them from tearing? I normally use food grad silicone. Very nice fittings. Sure as time goes, someone will make cheaper or similar product. Enjoy your channel, you KISS
To all of the many commenters asking for links to the alternatives, just stop. A quick search using keywords like "Imperial" or "Hvac quick disconnect" gets the results faster than it takes to comment asking for links. Second: *UA-cam does NOT ALLOW OTHER THAN YT VIDEO LINKS IN COMMENTS.*
You don't need even low loss fittings. If you're getting blow back you need to adjust the schrader depressor using a schrader removal tool/needlenose... I have 0 blowback or issues using standard fittings.
The kind of remarks I see here are the remarks that always happen when someone tries to introduce a different method to guys who are technicians in the field. I don't know why people don't just accept it on face value. It's another product, if you like it then buy it, if you don't like it then just move on. It's a cool product and I understand why it cost this much but at $200 it is not something that I would buy. I still appreciate the Video introducing me to a new product I had never seen before.

I would like to know if I can put a sequencer ( time delay ) after the contactor to my compressor and which load voltage line do I use . Do I put it on the black that goes directly to the compressor after the contacter or what . I know that I have to put 24 in line to the contact too the time delay . Put can this be done ? And will effect the compressor in any way. Other than 1) it will first make the condenser fan will start first and after a few seconds the time delay will make the compressor start. What do u think !!!!! And how
Not sure I'd want to store my lines and gauge set pressurized. Kinda like a torque wrench, always move it back to zero. I think wireless gauges would be better, very little loss. These built into the wireless gauge would be best.
Digital gauges don’t matter with that. You’re talking about old-school gauges and those are really good for probes because you don’t wanna mix refrigerant on the hoses so for like today when I’m doing maintenance on this 40 system hi rise today that would be really good for hooking up the probes for sure. ❤😊
Unless you have an actual problem with a unit, it is no longer considered good practice nor even necessary to check an a/c unit's refrigerant charge. You are better off only checking temperatures of the air intake and out, temperature of the lines, and temps in and out inside. And instead of these tools, you should use Accutools's valves that first attach to the lines, then attach your measurement tool, then they have screw valves that then depress the shraders to allow refrigerant in. Even then, only one is really necessary for the liquid line, and if you use probes, will not lose any siginificant refrigerant that needs to be fed back into the system.
Or, spend $20 for some charging valves… Basically, you attach the valve and then turn the screw to depress the Schrader… I use these and there is just too much variance is fittings and it allows you control over when the Schrader gets depressed…
While you are right the fact is the c&d valves still release a spay when disconnecting, about the same amount as low loss hoses, this is the why the $200 connectors were born… they eliminate that loss as small as it may be… to each their own 🤠
Come on man why are you trying rain on our parade I have spent 200 bucks on all kinds of dumb stuff smoking drugs women with no scruples these fittings won’t let you down but the other things I mentioned will .
I have a valve very similar to the 5050 that’s part of a hand pump I use to set pressure on the air shocks of my mountain bike. Once that valve is closed, anything that gets out after is from the hose (not the shock), not the system so any refrigerant that comes out will be in the tools hose no matter what.
I thought maybe $50 at the high side, but $200!! I rather lose a bit of freon.
Just wait till China start producing them. These are basically quick connectors that are used in car AC's. I predict you will be able to get them for less then $10.

Speak for yourself. Stupid to you but not to others.
@TheCherokeeKidd well, they are supposed to be very accurate and all that jazz..
So basically these are higher quality of these $9 ones?

I switch my gaskets the moment I see them wear and keep the valve depressor a bit tucked
I hardly have any leaking
I also don’t use hoses only probes
Just an idea for techs out there
I’ll go through a pack of seals per season
Not too bad. They’re like $10 bucks
I’ve been waiting on something like this. Hopefully they’ll be less expensive in the near future.
Equal or better options have existed for way less money for 30+ years.

You've just been watching youtube videos waiting to find out about new inventions that have been around for 40 years?
You need to get the F off your phone bro.... Just walk away
It seems convenient. I would not change over to prevent refrigerant burns. I would do it for the convenience of
Not having to twist on and off traditional fittings. It gets tedious after years in the trade
Amazing that these are just coming out now, I always wondered why we didn't have snap fittings like this.
I haven't used gauges in 5 years. Probes are the way to go. Thread the depresser in your tee and you don't lose refrigerant. Cool concept but won't fit in a lit of applications due to size.
Looks like a great product for test ports that are easily accessible and pointing in the right direction. Seems where you would need these the most you wouldn’t have the clearance, Clarence.
Show me how they work in the most common scenario. Make sure it's hot AF outside, have the system running and in the same continuous video frame, show me the loss using the conventional hose connectors and then with these unique adapters. And are the orings unique in size to the adapters, thereby marrying me to this company for a $50 bag of $2.00 orings every few months?
they are dam near impossible to get on when the pressure is high, hot day etc. Even on the low side.
😂😂😂😂
Hold my beer and give me damn hoses son. Gotta toughen them hands up 10 plus years hooking gauges up everyday.
I’ve seen those safety gloves get frozen into someone’s hand do not use!!!
20 years in the trade and I’ve never used gloves to connect gauges, also I’ve never been burned by refrigerant.
Really? Not once? In the past 35 years I have done it a few times because sometimes you're just dealing with a nightmare of a installation that some got away with and you just do the best you can.
@@KO-pk7df damn, 35 years in the trade! I have much respect for the veterans in the trade.
yea, I'm sure literally never. Smh. Ok dispatch.
@@ChristopherSugg - never once! Always had valves at the end of my hoses. How the hell would I burn myself?
@@July4.1776 oh idk failed core? Literally several reasons besides technician error that can cause it, which is how I know you're full of shit. The fact you are so confident in "never" is how I know you're just a liar dude.
Good luck getting those on a Goodman system
LOVE ALL OF YOUR ADVICE. THANKS SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!
When changing O rings I would lubricate them with vaseline or DC-4 to help them last, good info here. FLY NAVY!!!
And you'll end up contaminating the refrigerant in the process. The o rings do not ever need to be lubed in this application. If anything, the ONLY safe lube to use would be Nylog.
This is really good thing bro but I still lose some refrigerant left in the hoses. I try to return as much as possible by letting it go through the suction line but still some of it is always left in them. I guess it’s just a diminimus amount and you just can’t avoid it.
How? do you have valves at the end of your hoses?
As far as limiting refrigerant loss, I don't think anything works better than a thumb screw core depressor.
Okay so cool idea but that just made me think of an idea... why not just use pressure transducers to read pressures with out a manifold, so no long line set and you just want to see what pressures you're seeing in the system. Maybe make it so the low side has a port to add refrigerant so then you wouldn't need to disconnect anything and no loss at all....
$200 is more than many gauges themselves.
Yeah but if you do hvac full time you aint buying no 200 gauges
@@jeffreys1554 have you seen the Navac analog gauges? Plus that logic doesn't undo overpricing.

Tools tools tools! Great video, very informational! Keep up the great work!! ❤
I see you using these for this season but I’ll bet they’ll be tucked away in the “regrets” drawer by next season.
We will see
@@diyhvacguy the reason I say this is when I saw how the adapter connects to the hose “dock”, it makes it stick out very far and if anything presses down on it, the thing is gonna snap. I don’t have to connect hoses all day like a lot of techs so this might be great for you, but not for me. I’ll thread my fittings thank you.
May be a good investment with the new "reverse thread" systems coming out. Wont need to be buying adaptors or new hoses just for those.
Can these work of field piece probes?
25% of the reviews on amazon are 1 star. People are saying the O-ring pops out on the high side when you remove it. I think I'll wait until the price comes down and the reliability goes up.
Where have you been. Automotive techs have been using quick connects on ac recovery machines for over 20 years.
Am I in the automotive business? I think you know the answer 😅
I doubt that.
What about the injection of air? I'm not jumping on you. I'm just curious. How can you bleed out that air that exists within the chamber. I appreciate your time making this video.
I think that the Sealright hoses work great and are a fraction of the price. You lose an extremely minimal amount, if any, refrigerant. I've used these hoses for a couple of years now.
I got burned pretty badly in my first month, having to go to a burn center and be out for like a month almost, but that was before i knew about the two finger method... but there is certain situations where its basically impossible when its in a dumb spot, so this would be good for that but man i hope they dial that price back
$200 gets you nice coilovers set for a civic/crx
Nice is a strong word bruh.
Solowerks maybe. LOL
And who even talks about CRX's. You are OLD.... hahaha
@@jims.3987lol
I got a set 2y ago and they never worked but I will try again lol 2ed time may work thanks for the video
They require some technique for sure
Can you do a second review of them in full use? With unit running I’m thinking of ordering some
Currently Unavailable and $220 bucks. Yikes! The FF or frostbite factor is more of what I am concerned about! Wear good gloves to disconnect.
WHOA--at $219 for the 90 degree set (they're out of the straight ones) a strong pass, unless I was in the HVAC repair business
Looks like somthing a young kid would waist money on 200 bucks for somthing that will fit maby 60 percent of units I work on might suggest good pair of gloves for 20 bucks
True. There are a lot of units you could get one of these on and not the other. Im about to upgrade and get the job link setup. Those wireless/hoseless ones barely release any refrigerant. But, like these, they just can't be used sometimes.
Those fitting are to large in lots of situation. I used low loss fitting and they worked good. The best solution I found was to use a regular fitting with the hand operated shot off valve about 5 inches back on the hose so the refer loss is hardly nothing
I will recommend this tool to my customer who research capacitor price in Amazon.
I noticed a lot of people talking about refrigerant still being in the hoses. Do you not know how to easily suck it buck into the system? One of the first things I learned when being taught how to use gauges.
Nice, but won’t fit on a lot of units that has great design, sometimes u struggle to attach regular guage tip lol
Very nice! That is a time saver.
Yes it will save you approximately 1 second over existing low loss fittings that cost 20 dollars.
Thank You just put my order in for the Quick Fittings.
Why?
36 years in the trade, standard low loss fittings for a tenth of that price have served me well. I see no reason to purchase this item, especially at the ridiculous price.
They came and gave us some samples when I used to work at Johnstone. Very cool and high quality product, but too expensive and sometimes impracticable due to the clearance you need to connect.
We chose not to stock them and I’ve never seen anyone else with them. My current fieldpiece Joblink probes have the best connectors hands down. They aren’t the giant low loss, minimal and just great quality.
very cool fittings Thanks
just as recent as last week, r410a cost me $236 per 25lb jug. To think i would spend $200 for each set (straight and 90 degree) of these, is ludicrous to save a couple of squirts of refrigerant(especially, when the EPA said that a small amount of refrigerant loss is acceptable when connect and disconnect hoses). This is for the new techs only. As for seasoned HVAC+R techs, if you have been doing HVAC for a while, you know that there are, at least. three cheaper more effective ways to minimize refrigerant loss, than even the low loss fittings.
Brother I love it, but there’s some units their not going to work on because their so long and the idiot way they designed some of the old units. I love it though and would buy it.
Absolute game changer
You would think with the under the EPA’s standard minimum refrigerant loss that these type of connectors would be standardized and way ahead of their time. Usually a great deal of refrigerant is lost in tight areas in struggling to get on and off especially high side.
Amen.
What lube can be used on O Ring to keep them from tearing? I normally use food grad silicone. Very nice fittings. Sure as time goes, someone will make cheaper or similar product. Enjoy your channel, you KISS
This type has been around for decades, 41 years doing hvacr
Wish they worked properly, excellent idea.
My YJ R134A connectors lock on and then screw down to open the valve. Reverse to remove. Nothing but the slightest pop when disconnecting.
I like it bro good job for always trying to better yourself
To all of the many commenters asking for links to the alternatives, just stop. A quick search using keywords like "Imperial" or "Hvac quick disconnect" gets the results faster than it takes to comment asking for links. Second: *UA-cam does NOT ALLOW OTHER THAN YT VIDEO LINKS IN COMMENTS.*
You can buy the CPS core depressors for 1/4 of that price.
You don't need even low loss fittings. If you're getting blow back you need to adjust the schrader depressor using a schrader removal tool/needlenose... I have 0 blowback or issues using standard fittings.
all in a days work...Amazing!
Not a bad idea, but my NRP hoses have very good low loss fittings
Or you can use low loss fititngs, but they are getting mildly pricy. I use $12 c&d core depressors. Very simple. And a little bit more cost effective
The kind of remarks I see here are the remarks that always happen when someone tries to introduce a different method to guys who are technicians in the field. I don't know why people don't just accept it on face value. It's another product, if you like it then buy it, if you don't like it then just move on. It's a cool product and I understand why it cost this much but at $200 it is not something that I would buy. I still appreciate the Video introducing me to a new product I had never seen before.
Even at this price and with naysayers, the maker
has them listed as "Not Currently Available".
So, I guess Someone is buying them. 😁✌🖖
price price price enough said
Yes everyone should see if they can afford things before purchasing. America really has a problem with this, so thanks for the reminder haha
I don't think the guy is saying that he can't afford it I think he's saying it's too much for what you're getting there is a big difference there buddy ... I do think you make good videos though @@diyhvacguy
These definitely look cool. I might get these.
If you’re getting a refrigerant burn from a low loss fitting, it’s either bad gaskets/rings or user error…
Do they make them for 5/16'' ports that are used on some mini-splits?
I would like to know if I can put a sequencer ( time delay ) after the contactor to my compressor and which load voltage line do I use . Do I put it on the black that goes directly to the compressor after the contacter or what . I know that I have to put 24 in line to the contact too the time delay . Put can this be done ? And will effect the compressor in any way. Other than 1) it will first make the condenser fan will start first and after a few seconds the time delay will make the compressor start. What do u think !!!!! And how
I thought like $50 for both max.. but $320 ?! Fuck that ! 😀
😂
Why are they not available to buy anywhere?
Imperial part number 16C and 17C. Available from Zoro tools or Amazon.
Not sure I'd want to store my lines and gauge set pressurized. Kinda like a torque wrench, always move it back to zero. I think wireless gauges would be better, very little loss. These built into the wireless gauge would be best.
A true tech does not leave pressure on his gauges.
It took me long to figure it out no one ever thought me til it clicked one of these days
Talking about cycling all the refrigerant into the system from the gauges?
Wanna bet?
No such thing as a true tech. We are all just wanna be’s
Digital gauges don’t matter with that. You’re talking about old-school gauges and those are really good for probes because you don’t wanna mix refrigerant on the hoses so for like today when I’m doing maintenance on this 40 system hi rise today that would be really good for hooking up the probes for sure. ❤😊
That’s pretty 😎 cool do you have the link for it?😊 expensive but I can definitely use a special we use every day.
CPS safemate hoses are far cheaper and work great
Unless you have an actual problem with a unit, it is no longer considered good practice nor even necessary to check an a/c unit's refrigerant charge. You are better off only checking temperatures of the air intake and out, temperature of the lines, and temps in and out inside.
And instead of these tools, you should use Accutools's valves that first attach to the lines, then attach your measurement tool, then they have screw valves that then depress the shraders to allow refrigerant in. Even then, only one is really necessary for the liquid line, and if you use probes, will not lose any siginificant refrigerant that needs to be fed back into the system.
I use stub gauges with a charging tee and ball valves.
@@thisisyourcaptainspeaking2259 yep, even were available in analog form. But rarely anyone used them.
Is there a part number for this or link for this item , interested
Or, spend $20 for some charging valves… Basically, you attach the valve and then turn the screw to depress the Schrader… I use these and there is just too much variance is fittings and it allows you control over when the Schrader gets depressed…
They come from China, and that is why they are oriented.
Not available anymore on Amazon
won't fit any 410A systems
While I appreciate new tech....this is a waste of $200. You can just buy flow control valves for $20. (C&D CD5050).
While you are right the fact is the c&d valves still release a spay when disconnecting, about the same amount as low loss hoses, this is the why the $200 connectors were born… they eliminate that loss as small as it may be… to each their own 🤠
And the new ref is ganna make all this not work
C&d valves suck bit of mine went out within a month
Come on man why are you trying rain on our parade I have spent 200 bucks on all kinds of dumb stuff smoking drugs women with no scruples these fittings won’t let you down but the other things I mentioned will .
I have a valve very similar to the 5050 that’s part of a hand pump I use to set pressure on the air shocks of my mountain bike. Once that valve is closed, anything that gets out after is from the hose (not the shock), not the system so any refrigerant that comes out will be in the tools hose no matter what.
How do you start in one corner?
How do you pull/replace Schraders with these in place 🤷♂️🤦♂️
one thing i have learned about this channel is its from bizarro world
