All ball valves are factory cleaned for oxygen service and conform to NFPA 99 standards. Each 1/2″ to 4″ valve consists of Teflon seats and adjustable stem packing gland with a Teflon stem seal. The 2-1/2″ and 3″ valves Consist of Teflon seats and double Teflon stem seals.

All ball valves are rated at 400 psig, as well as full vacuum (29.9″ Hg). Valves go from full ON to full OFF by turning the vinyl-gripped valve handle 90°.
