ASTM A403 WP304 Stainless Steel Couplings

ASTM A403 WP304 Stainless Steel Couplings are compact industrial fittings used to join two sections of pipe or pipe to a nozzle or swage. As a wrought fitting, the material, WP304, is the pipe fitting equivalent of the B8 bolting grade, manufactured from austenitic stainless steel (AISI 304). Couplings are available as Full Couplings (threaded or socket-weld ends) or Half Couplings (one threaded or socket-weld end and one plain end for welding onto a vessel). These components are vital in systems that require exceptional corrosion resistance and thermal stability, such as chemical lines, instrumentation ports, and boiler connections. The use of the WP304 grade ensures the connection point maintains the same high-level integrity as the B8 bolts used throughout the system. Zeron Fasteners manufactures and supplies these fittings, guaranteeing compliance with dimensional standards and the metallurgical demands for secure, high-pressure piping connections.
