A very good video on push to connect fittings. I hope there is a part 2 where you test the pressure ratings of these fittings. If they work as advertised they would definitely be a game-changer!
I used them this spring on mini split line set that was to short, 30' up on ladder under soffit (solo) very hard to flare so I gave them a shot so far so good. Ty thanks so much for the Videos and what you due for the HVAC community Thanks again !
So the forward pressure of the copper tube is what creates the seal. That thing that bites down on the pipe, the silver washer, pushes the see-thru plastic piece forward. The two O-rings are squashed by that pressure, narrowing edge-wise while expanding outward and inward. That's the seal. It's dependent on pressure on the O-rings, but the retainer ring mars the surface. It scratches grooves into it as you push it in. Maybe that extra see-thru plastic piece stops those scratched channels from leaking to atmosphere.
Looking forward to your next video on checking pressure with this new connection but I know some are thinking this is similar to pex piping that they sometimes use for plumbing, most may feel it's taking away their jobs. SHALOM to ya brother
Great information. I like old school n keep it simple. Everything coming out with new technology n this is better seems to end up costing customers more money in the end, service calls for sensors failing control boards that some MIT student created etc.. I do like ur idea about quick connections for checking pressures etc. Time will tell I guess. For now I'll stick to brazing. Thanks ty! 😊
This is the.. Copper vs pex Wire nut vs wago Sweat vs shark bite debate This is Dial-up vs fiber optic IMO. pressure system engineers spent a lot of time on these fittings and are confident that they will work… So much so that they’ve been put the market
Enjoyed this video, for people like me working in tight space on the indoor inverter of my mini split the sm line 1/4" snapped when trying to make the 90-degree bend. Brazing is out of the question. Will be a challenge but with an elbow Quick connect gives new life to my inverter which otherwise would be useless. Have two systems the other is running great! Without any drama, (WHY ME)😢.... STILL NOT OUT OF THE WOODS YET.
Yes I can see it used as test ports on various sizes exp in they get large enough to also isolate 3/4 & 7/8 suction lines also ..following Thanks for the schooling
I have been wondering that same thing myself. I haven't been able to bring myself to use the connection in a permanent instation. I do use them for pressure testing lines. I have not used the nylog on them for that purpose just to keep the oil from atacting dust when they are not in use. I guess we could use it on one side and not the other and see wich started leaking first.
I don't know what brand it was, but I found one of those fittings leaking on a minisplit system. Tight spot. Original installer didn't want to braze. Leaking refrigerant oil into the insulation. Sure is better than the fire risk. It seems to really want a straight as possible pipe shoved in. I don't know what the success rate on those are.
It’s worth installing and testing on a dummy system and have it run for awhile . It’s the shark bite of hvac fittings . Most plumbers will say shark bites are only good for emergencies or the DYI homeowner . This will open up a can of warms in the DYI community .I could see the EPA getting involved and removing it from the market .
@@sebastiantevel898 yes but if you’ve ever had to change out a evaporator coil in a 150 degree attic . You just want to be finish the job quick . There also the part of carrying heavy brazing equipment not to mention you can burn 🔥 a house down if your not careful
You can buy refrigerant for your car easy as you please. How may shade tree guys accidentally release each year ? The government only cares when they can tax it.
Have you seen the SmartLock Fittings? I have not seen much about them on the web yet (reviews), but they look interesting. The biggest difference I see is they are metal-on-metal compression and do not use O rings, They have a 25-year life. You can also use them on flare fittings, which I think is crazy. I would love to have you review them. Thank you for all your videos, I know they are hard work and take hours to complete.
also i think these is the future that we will have to use because of the new blends being basically propane for the 90 degree its the restriction that causes the the elbow mawp at 650 if the start making a long radius and open more smooth 90 I think it will get the psi up to 850
The newer ways of joining copper tubing without flame are going to be more and more the SOP in places where a hot work permit and a fire watch are required. Your commercial client's Safety Manager doesn't care if that fitting leaks out in 5 years. He wants to reduce his paper work, keep his ass covered, and avoid any of the risk inherent with hot work.
If one uses it as you said, for a quick connect to check pressures would that not leave an open ended pipe in the system? I am not sure I understood your analogy. Looks interesting. Similar reactions from tradesmen to Pro Press and Hubless connections in cast iron from plumbers when that eliminated lead and oakum joints.
One for the suction side, another for the high side when pressure testing coils or line sets. Looking for leaks. Cut the coil out and stick these on real quick. I'll do a video on it soon and use it.
Hopefully that’s what two o-rings are for- one for pressure differential each way ( in flow, outflow). Many push fittings are only designed for pressure not for vacuum.
King valve is on a liquid receiver. As for the service valves I'm not sure, they do have reducers that might work. They do have adapters for ductless flares fittings and they also have a service valve with the push to connect already on one side. rectorseal.com/quickconnect-lp
Ty . Question for you. I was doin a vacuum pull down today and suddenly my micron gage was going crazy. I valved the ports off, I disconnected the hose that I was using for the vacuuming and it was full of oil. It’s a vacuum pull down with just one hose through the high side.Do you think the oil in the hose was from the pump or the compressor?
It's the oil from the unit A few possibilites 1 Oil could have been trapped in the suction line at a low spot as the vacuum pulled down the higher pressure on the other side pushed threw and carried the oil with it. 2 refergerant still saturated with the oil in the compressor, as the vacuum drops the refergerant violently boils and carries the oils as its pulled out. 3 evaporator higher than the condensors as the vapor is pulled out some oil flows with it and and collects at the low point at the suction port. 4 oil logged in the evaporator as tje pressure changes the vapor moving towards the suction side siphons the oil with it. 5 a continuation of if the above. Be sure and clean you hoses out after that. Roll flush or alcohol (or what ever the manufacture suggests) so the oil in the hoses does not collect moisture and low down the next vacuum or worse turn to an acid and contaminate your vacuum pump.
Keep using those fittings boys, I charge $750 to replace after they fail. I am able to buy my wife a Tesla and putting my kids through medical school because of those fittings. 😂
One thing I do know is you still have to clean the copper. I don't care if it's just a plain compression fitting it must be cleaned. (should IMO) Brazing may take longer,but speed kills! 🍺🍺🍺🥃🥃🍇🏌🏻♀️ Stay safe. Retired (werk'n) keyboard super tech. Wear your safety glasses.
The pro-press and pro-fit work, I have not tried these. They are not inexpensive. They keep residual from brazing out of the lines, but I have never had that problem with Stay-Silv and NO Flux. Time will tell.
Like others have said, this is the Shark Bite of HVAC. I don’t think I’d use it. However, I think that the future of HVAC is a braze free installation. When you look at leak points, most of them are at the braze joints. I think I’d have more confidence in crimp connectors.
@@love2hvac Correct me if I’m wrong but aren’t there hundreds of small braze joints that make up an A coil ?? I guess the point I’m trying to make is that no matter where you put a braze joint ( or solder joint) you leave yourself open to a compromise in the copper tubing. In a perfect world, it would be made from one continuous piece of tubing. Your thoughts please .
@@love2hvac BTW and most importantly, love the videos and the information you provide. I wish that I got into the HVAC field 20 years ago 👍. Thank you.
Let’s see, I did some research here, it seems one stick of dynamite has the energy equivalent of 1MJ, and one litre of propane or about 1.1LB has the energy equivalent of 25.3MJ or 25.3 sticks of dynamite hahahaha, It seems I was underestimating the explosive potential of propane by more than a factor of 10 when I said a pound of propane was equal to only two sticks of dynamite, it’s more like 25 sticks of dynamite. Well that explains what them exploding refrigerators I googled look like, with only an ounce or two of R290 or “PROPANE” as a refrigerant that’s the explosive potential of one and one half to three sticks of dynamite. This is nuts, I checked this over several times because I find it hard to believe myself but math doesn’t lie.
one litre of Gasoline is around 34.5 MJ 15 gallon tank of gas in a car is 56.781 liters = 1,962.0495 MJ Your driving around with 1,962 sticks of dynamite 🧨 right behind you. That's a lot of dynamite, are you still planning on driving?
Ty Branaman Got no choice, unlike refrigerators the internal combustion engine will only run on fuels that burn, besides some woman called me with a clothes dryer down, considering raising my rates though !
If you cant solder just say so!, Southern men think this is another diversifying Yankee joke, It's too expensive to use! investing in the crimp tool that is necessary is being avoided here.

I hope you didn't offer any warranty on your work. I have replaced those fittings. After one harse season, those rubber and plastic fail

Great option for diy, tight spots, time sensitive install... I may go this route on my next ac update at house
I agree… Def the preferred fittings when working on systems using propane… love your channel bro… keep ‘em coming 🤙🏽

I agree proper brazing is unbeatable.
How long. Before pex refrigerant piping comes out 😬😬
@@love2hvac I like to keep things simple.
Actually with brazing, the join is stronger than the proper pipe. I love brazing.
This is the..
Copper vs pex
Wire nut vs wago

This is Dial-up vs fiber optic IMO.

I am old school braze guy….but…this video made me rethink push on fittings. May try a few to see how they work out. Good video.

I wonder if you can use Nylog on the connections to help seal and protect the O rings from possible damage.
I have been wondering that same thing myself.
I haven't been able to bring myself to use the connection in a permanent instation.
I do use them for pressure testing lines. I have not used the nylog on them for that purpose just to keep the oil from atacting dust when they are not in use.

True. Yet flaring a pipe does not require Formula 1 engineering level of mastery. A DIY with decent skills and who does not rush, can do it properly.

Units do not belong in unconditioned attics.
Foam the roofline, remove the ceiling insulation.
Home performance goes up, working hazards go down.
You can buy refrigerant for your car easy as you please. How may shade tree guys accidentally release each year ?
The government only cares when they can tax it.
@@love2hvacdoing this in the south isn't very smart, but neither is putting your unit in the attic. Sadly builders suck down here
Those would be nice on a job where you’d want to change filter dryers on after a burnout.
That's a great idea!

These fittings will be good for those who do events where they install temporary air conditioner and temporary cold rooms and so on.

I wouldn’t mind using that in very tight spaces or for installing txvs.
Ford used these type of fittings on my 89 Mustang a/c lines.
How's it going?

Are these EPA certified? If they passed it. I don't mind using it.
if i remember correctly you should be able to service these you unscrew the cap and replace or lube the seals.

I wonder if you can pull 200 microns on a system with those fittings?
That's a great question.
If you can’t they’re leaking ! I’ll stick to brazing.
Hopefully that’s what two o-rings are for- one for pressure differential each way ( in flow, outflow). Many push fittings are only designed for pressure not for vacuum.
@@nunyabusiness6746
Say something... then add "I'll stick to brazing!" after each thing you say! That's basically all UA-cam Push Fittings videos! 😆
But do they seal and not allow fluid to escape when they disconnect? If so that is really nice
No they don't seal at all
Is there a way to disconnect it without having the tool
Anyone know if they can handle compressor heat, over time?
Do they make those push connect fittings that will hook up to the king valves on the condenser
King valve is on a liquid receiver.
As for the service valves I'm not sure, they do have reducers that might work. They do have adapters for ductless flares fittings and they also have a service valve with the push to connect already on one side.
