The B&K 511-385HC is a 2-inch x 1-inch galvanized reducing coupling from the ProLine Series, designed to connect two male-threaded pipes of different diameters in a secure and corrosion-resistant manner. Manufactured from galvanized malleable iron, this fitting is engineered for strength, durability, and long service life in a wide range of plumbing and industrial applications.

The coupling features female iron pipe (FIP) threads on both ends, allowing for easy installation and a tight seal. Its zinc-coated finish provides excellent protection against rust and corrosion, making it suitable for both indoor and outdoor use. This fitting is ideal for systems that transport potable water, compressed air, drainage, gasoline, diesel, alcohol, and other fluids requiring rust-resistant containment.
