The B&K Products 511-375HN Galvanized Reducing Coupling is a premium-quality fitting designed to connect two male-ended pipes of differing diameters. Constructed from galvanized malleable iron and coated with zinc, this coupling offers excellent rust protection and long-term durability, making it ideal for both residential and commercial plumbing systems.

This reducing coupling is versatile and suitable for a wide range of applications including potable water systems, compressed air lines, drainage, and DIY plumbing 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.

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