Product Details
300lb black iron unions are designed to connect two sections of threaded pipe while allowing for easy disassembly and maintenance, making them ideal for systems that require periodic service by enabling quick removal and reconnection without disturbing surrounding piping. Constructed from durable malleable iron with a black finish, these fittings provide 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, the unions are pressure tested for performance and consistency, conforming to ASME B16.3 dimensions, ASTM A197 material specifications, and ASME B1.20.1 threading standards to ensure proper fit and function.
