Review on 🛠️ Milton Industries Brass Body S-765 HI-Flo V-Style FeetA, M, V 1/4-Inch MNPT Single by Smooth May

I have my second and final set of these quick disconnects. The female end will not close when you disconnect the air tool and depressurize the air line until you turn off the compressor or regulator. Because of this, I added ball valves to my air lines to shut off the air supply. I understand that after a period of heavy use, air fittings fail to hold air. They didn't last as long as my last set (different brand, no longer in production) which was 4 years old. The current plug has only been in operation for 6 months.
