The B&K 511-002HC is a 3/8-inch galvanized malleable iron cross fitting, designed to securely connect four intersecting pipe sections in plumbing and mechanical systems. As part of the ProLine Series, this fitting is engineered for strength, corrosion resistance, and long-term performance in both residential and commercial applications.

This cross features four 3/8-inch FIP (Female Iron Pipe) threaded connections, allowing for a secure and leak-resistant junction. The galvanized zinc coating provides a protective barrier against rust, making it suitable for indoor and outdoor use. The malleable iron construction offers the strength needed for high-pressure systems while maintaining a degree of flexibility for a tight seal.

Rated for up to 300 PSI and temperatures up to 347°F, this fitting is ideal for transporting a variety of non-potable fluids and gases, including hot and cold water, compressed air, gasoline, diesel, alcohol, and low-pressure steam.
