Review on JACO Quick Connect Hose Fittings by Cho Screeton

I bought these because I need a quick connect air fitting for my shop air compressor. The one from the "hardware store" was leaking and I used to have to put a ball valve in front of the coupling to avoid the "not good" seal in the coupling. I've heard JACO did the best, or at least that's what the reviews say. So I bought this kit and installed one of the clutches on my air compressor. For 3 days the pressure in the tank has not changed. Still sitting at 120psi. That's exactly what I wanted. Sale. Worth every penny if you ask me.
