I thought maybe $50 at the high side, but $200!! I rather lose a bit of freon.

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.

That connection looks amazing! I like to hear the sound when the quick coupler connecting to the valves. 😊

[Jason-wcfh]

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.

First time seeing those connectors. Will have to try them out. They look like a game-changer!

[bigd]

I have quick disconnects on my manifold hoses I've had for 30 years. A two piece connector. Similar principle, different design.

[ChristopherSugg]

Yea, we have them, good luck with the high side right now on high pressure refrigerants. Hope they figure it out.

[MK-xltt]

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.

IMPERIAL QUICK COUPLER $20.00 AND $30.00 FOR 90 DEGREE ONE. I HAVE USED THESE FOR YEARS.

[wiley]

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.

Thank You just put my order in for the Quick Fittings.

[Raysmaintenance]

I got a set 2y ago and they never worked but I will try again lol 2ed time may work thanks for the video

[dgapp]

That price, ouch. Just get some Yellow Jacket 45 degrees low loss fittings. Lower profile and work great.

[AJ-oxxy]

These definitely look cool. I might get these.

[dgapp]

Fieldpiece (JL3) and Testo (an others) make wireless pressure probes that you can connect to low loss fittings. Almost zero refrigerant loss.
You can also connect a tee fitting for charging (with a hose of course)

[wkpowzr]

Looks like a quick way to connect if you've looking to shave seconds off a job hah! They are pretty clunky though and not every system will have the clearance. I like to use gas retention valve/ core depressor with a T for limiting refrigerant loss. Smart probe on one, and other open for whatever be it charging, micron gauge, etc.

[aperson]

Those are really neat, but WOW are they proud of them!!!! $219 for the 90* ones (straight are unavailable).

[HEFTYLEFTY]

I like it bro good job for always trying to better yourself

[stevekaufmann]

All you need are valves and the knowledge to close the liquid line and evacuate your hoses before disconnecting and be fast

[USNveteran]

When changing O rings I would lubricate them with vaseline or DC-4 to help them last, good info here. FLY NAVY!!!
