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. Constructed from durable malleable iron with a black finish, these couplings are suitable for higher-pressure applications and are commonly used to step down or step up pipe runs without adding additional fittings. Each fitting includes full lot traceability, and material test reports are available upon request to support quality and compliance requirements. Manufactured in an ISO-certified facility, the 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.
