Air Conditioner Ball Valve 1/4" SAE Adapter, Straight Shut-Off Valve for HVAC A/C Automotive Service Tools, Fits for R134A R22 R12 R410A Refrigerant

Worked for me on a mini-split install.

FYI I am a professional refrigeration service tech. The actual valves I received have a rubber coating on the valve handles. The pictures shows without The valve to Schrader seals work well and may even be better than the black rubber ones. All in all they seem to be made well and should stand the test of time. For the price if the last a year I think they are worth it. Even the name brands eventually fail!.

Not much to say other than it does what it suppose to and it holds without leaking. I had quick disconnects with shut off valves on the high and low side of a gauge set but didn't have anything for the center vent lines. Needed a shut off valve to place on the vent line (yellow) of a gauge set. Had this valve attached to the end of the the manifold gauge set vent line and it allowed me to quickly change over from a vacuum pump to a refrigerant tank without losing or having to purge the vent line when switching over from a vacuum pump to refrigerant tank. I don't use this everyday so I can't really say the longevity of the valve but for what I need it for it works perfectly fine. When I'm done using it, I leave it on a refrigerant bottle as a second shut off valve just in case the tank valve leaks while in storage.

Well, only last one month. I was using it constantly to check pressures for almost a month, then started leaking refrigerant. But I guess that what we get for the price.

do multiple repairs on automotive type A/C systems these adapters make it possible to hook up to whatever system that comes along for evacuating and recharging. all in a way that allows me to save Freon to and use it back in the same system without polluting the air with used refrigerant.

Good price

The media could not be loaded. They leak, what can I say? I needed them for a project this weekend but now it's not going to happen because these pieces of junk won't hold a vacuum to save their life.These things are total trash. Don't waste your time with them.UPDATE: The seller offered me a refund without being asked. As far as customer service goes, that is going above and beyond. Thank you for the offer, I appreciate it. Unfortunately, I can't take it in good conscience. I unsoldered the valves I purchased and used the parts to make a pair of valves that worked so I believe I got some use out of them.

The ball valve of this unit works good but the seal on the screw-on (female) end ripped the first time it was screwed on. I replaced the seal with one from Yellowjacket and it seems to work fine now. Probably a fluke and replacement seals are not expensive. And probably still a good value for the price.
