Product Details
300lb galvanized iron caps are designed to close the end of male-threaded pipe in systems requiring higher pressure ratings. These fittings are ideal for system termination, testing, or temporary shutoff, providing a secure, leak-resistant seal in demanding applications. Built with a heavier, more robust design than standard 150lb fittings, they deliver added strength and durability. Hot-dip galvanized to ASTM A153, they offer 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 caps are pressure tested and conform to ASME B16.3, ASTM A197, and ASME B1.20.1 standards for consistent fit and performance. Warranty terms are provided with the product.
