Nice kit
Size: 0.375 inches
Works just fine

Ok
Size: 0.375 inches
The only problem I had with it is that where the valve threads onto the hose it was very hard to get to stop leaking. I took it off three times and finally added several rounds of thread tape much more than it should take but for the moment it's not leaking. UPDATE It's still leaking. Tired of trying. Starting return. I do not recommend! ... show more

Fits up nice. Good kit at a good $
Size: 0.375 inches
Works well. The compressor kicks on very infrequently, so I'll check for any kind of minute leakage from the 90 deg shutoff valve. Else, threads up nice and appears to be fully functional. Kind of hard to use the hose clamps due to my vertical compressor leg configuration. Else, all good. Will update IF it's a valve leak of any kind. ... show more

Leak air
Size: 0.375 inches
Connectors leak air. It is due thread is not tapered enough to build a seal.
