Chrome plated brass shut-off valve with integrated back check valve. Works great for shutting off individual gas lines. Direction is one way from the 1/4″ male pipe thread thru valve body to 1/4″ male flare thread. The male flare thread allows you to choose the hose barb that works best for you. It also allows you to remove the hose from the valve by unscrewing the flare nut instead of having to cut the line or remove a clamp.
