Giant Buttonhead Fittings

Available in standard or Full Flow design. Both designs have a single check that provides the primary seal. The vent cap is a secondary seal and retards corrosion of the fitting face. Used on gate valves, such as WKM and Cameron, and ball valves such as Cameron, Grove and FMC having large capped fittings. Use a Val-Tex WKM or CIW-GB adapter for lubrication.
