The B&K 1-1/2-in x 1-1/4-in FIP Galvanized Reducing Coupling is a durable and corrosion-resistant fitting designed to connect two male-ended pipes of differing diameters. Constructed from galvanized malleable iron with a protective zinc coating, this coupling is ideal for applications requiring rust-proof performance and long-term reliability.

This fitting is suitable for a wide range of uses, including potable water systems, compressed air lines, drainage setups, and various DIY plumbing projects. It performs effectively in both hot and cold water systems, as well as in refrigeration, sprinkler systems, and fluid transport involving gasoline, diesel, and alcohol. The coupling is part of B&K’s 150-lb class malleable fittings, which are known for their ability to form secure seals due to the relative softness of the metal.

Threaded ends conform to ANSI/ASME B1.20.1 standards, ensuring compatibility with standard piping systems. With a pressure rating of up to 500 PSI at 150°F, this coupling meets rigorous performance standards and complies with NSF/ANSI and ASME certifications, making it a trusted choice for professional and residential installations.
