The B&K 511-228HC is a robust and corrosion-resistant galvanized merchant coupling designed for pipe repair and connection in demanding plumbing and industrial systems. With 2-inch Female Iron Pipe (FIP) connections on both ends, this coupling is ideal for joining or repairing pipes of matching diameter, especially in systems requiring rust-resistant performance and high pressure tolerance.

Crafted from galvanized malleable iron and coated with zinc, the coupling offers superior corrosion resistance and long-term durability. It is part of the 150-lb class of malleable fittings and is engineered to meet ANSI/ASME B1.20.1 threading standards, ensuring a secure and leak-resistant seal. The relative softness of the metal enhances sealing capability during installation.

Rated for up to 500 PSI at 150°F, the 511-228HC meets ASTM and ASME specifications and is NSF/ANSI 61 and 372 certified, making it suitable for potable water systems and other fluid transport applications.
