Suitable Conditioning Refrigerant Charging Recovery Review

Used primarily for 404a and is not vacuum resistant. Slight leaks at 275+ psi. For the price they work ok but they leak so you get what you pay for.

They arrived on time and appeared to be preserved, but one of them started leaking freon during an AC repair. I had to disconnect and upon inspection found a dangling handle on the yellow ball valve.

i put them on my yellow jacket gauge hoses and when i used them for the first time they leaked so badly that i had to take them off quickly if i wasn't wearing gloves would easily burn the refrigerant, don't buy them!

they have black gaskets at the top, they fall out and you don't know that this leads to a leak in the connection expensive freon goes into the atmosphere. no purchase recommendation. THE AIR FAULT PROBLEM needs to be solved immediately as it will harm the environment.

Used for HVAC at 25 micron vacuum and 200psi and they don't leak. I always add some compressor oil to the fittings, maybe that does the trick. You need good tubing to get 25 microns. You don't have to over tighten them for a vacuum as the vacuum will strip the seals.

I'm an HVAC service technician. I started using them a few weeks ago and for the most part they work great. They leak a very small amount of refrigerant when connected to the service port. The only problem I found with them is; If there is pressure at the end of the gauge and it is not connected to the unit, a small amount of refrigerant may leak through the valve. This is a very minor issue and I recommend this valve.
