The B&K Products 511-310HC Galvanized Reducing Coupling is a compact, corrosion-resistant fitting designed to connect two female-threaded pipes of differing diameters. Manufactured from galvanized malleable iron and coated with zinc, this coupling offers exceptional rust protection and long-lasting durability, making it ideal for both residential and commercial plumbing systems.

This reducing coupling is suitable for a wide range of applications including potable water systems, compressed air lines, drainage, and custom DIY projects. It performs reliably in hot and cold water systems, refrigeration setups, sprinkler installations, and fluid transport involving gasoline, diesel, and alcohol. The inner rust-proof protection ensures clean and safe fluid conveyance.

Threaded ends conform to ANSI/ASME B1.20.1 standards, ensuring compatibility and a secure seal. The malleable iron construction allows for a snug fit due to the relative softness of the metal, which helps prevent leaks and enhances system integrity.
