Product Details
300lb black iron reducing couplings are designed to connect two sections of threaded pipe with different diameters, providing a straight transition between sizes. Commonly used to step down or step up pipe runs, they offer a compact and reliable solution without adding additional fittings. Constructed from durable malleable iron with a black finish, these fittings deliver the strength required for higher-pressure applications. Each fitting includes full lot traceability, with material test reports available upon request to support quality and compliance requirements. Manufactured in an ISO-certified facility, these couplings are pressure tested for performance and consistency. They conform to ASME B16.3 dimensions, ASTM A197 material specifications, and ASME B1.20.1 threading standards for proper fit and function.
