The Western Enterprises DC-540 Brass Compressed Gas Dust Cap protects CGA-540 oxygen fittings from dust and contamination in industrial gas control and manifold connection systems. Made of brass with a female CGA-540 connection, right-hand threads, and a one-piece construction, it is designed for oxygen gas equipment and manifold assemblies used in welding systems and industrial gas distribution equipment. The seal is not gas-tight, reflecting its primary role as dust and contamination protection for oxygen service in industrial gas manifold systems.
