The B&K 510-165HN Reducing Elbow is a high-strength, corrosion-resistant fitting designed to connect two pipes of different diameters at a 90-degree angle. Made from galvanized malleable iron, this elbow is engineered for durability and long-term performance in both residential and commercial plumbing systems. Its zinc coating provides rust protection, making it ideal for indoor and outdoor use.

This elbow features female iron pipe (FIP) threaded ends, allowing for secure, leak-resistant connections with standard NPT pipe threads. It is suitable for a wide range of applications including potable water, compressed air, fuel systems, and industrial piping. The malleable iron construction offers a balance of strength and flexibility, ensuring a tight seal and easy installation.
