The B&K Products 511-203HN Galvanized Coupling is a high-quality fitting designed to create a secure and leak-resistant connection between two pipes of equal diameter. Constructed from galvanized malleable iron, this coupling is coated with zinc to provide superior rust protection, ensuring long-term durability even in demanding environments.

This coupling is ideal for a wide range of plumbing and fluid transport applications. Whether you're working on potable water systems, compressed air lines, drainage setups, or custom DIY projects, this fitting delivers reliable performance. It’s also suitable for hot and cold water systems, refrigeration, sprinkler installations, and the conveyance of gasoline, diesel, and alcohol.

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