Review on Beler Fitting Connector Fulfilled Hermeshine by Genene Locson

Bought this valve to control the gas from two gas tanks to the engine. When I first installed one of the valves, the knob rotated but slipped off the valve stem and damaged the plastic knob. I was able to get it to work temporarily by tightening the screw that holds the handle (IF YOU BUY, TIGHTEN THE SCREWS BEFORE USE). I bought a second of these valves to get a new grip. Yesterday the original valve started leaking at the valve stem with constant dripping so I replaced it with the second valve. I will buy another better valve to replace it.
