Review on 🔧 Enhanced QWORK Air Tank Manifold: Safety Valve, Fill Port, and Relief Bypass for Optimal Performance by Keyone Brownlee

Don't waste your money on this. The valve does not close completely. I thought the plastic button (not metal as the description states) might have prevented it from coming off completely so I removed the locking ring, popped out the button and twisted to loosen it completely and it's still leaking . . At the time I had about 90 pounds of air in my bladder. I received 2 of these as the 2nd was a replacement for the first as it was defective and breathable. Apparently they just do it and don't test anything to see if it actually works.
