Product Details
300lb galvanized iron reducing couplings are designed to connect two sections of threaded pipe with different diameters in systems requiring higher pressure ratings. These fittings, ideal for stepping down pipe size, provide a simple and efficient transition without additional components. Built with a heavier, more robust design than standard 150lb fittings, they offer added strength and durability for demanding applications. Hot-dip galvanized to ASTM A153, they provide strong corrosion resistance for extended service life in harsh environments. Each fitting includes full lot traceability, with material test reports available upon request. Manufactured in an ISO-certified facility, these couplings are pressure tested and conform to ASME B16.3, ASTM A197, and ASME B1.20.1 standards for consistent fit and performance.
