Pretty nice connectors

I really liked these connectors compared to the mountain connectors also available here. They were easy to use - they snapped in and out just like you would expect. This is not the case with Mountain brand connectors which tended to get stuck in the HI Press connector. These connectors also have a built in rotating on/off wheel. This gives you positive control while Mountain connectors don't. Those are good shots.

Pros
  • Blue and red switch Material: high quality aluminum
Cons
  • No power

They work as they are supposed to

I have used these adapters at least a dozen times and so far they are working as they should. I read several reviews that said they had trouble removing the high pressure coupler after using it. I dip my pinky in compressor oil and stick it in the end of the coupler before I put them on to lubricate the small ball bearings in the pair and they come off with little to no effort. I would buy them again and recommend them to a friend.

Pros
  • Adjustable coupling provides universal compatibility with all models
Cons
  • So far so good

Thought it would be better

Bought these along with others to replace coupler adapters with the HF (Pittsburgh) A/C manifold kit. The low frequency coupler on the HF set doesn't seem to last long. Although it never failed. Also, they just "didn't feel" that they would last much longer. So I got her. After only 3 or 4 uses I decided to pressure test my manifolds, hoses and couplers with nitrogen. This test revealed a ruptured seal on the high side clutch which can be seen in the photos. Couplings must not allow…

Pros
  • Precise snap and knurled ring for ease of use, detachable adapter for longer life
Cons
  • Volume
