About this item

The B&K 520-165HP Reducing Elbow is a heavy-duty, precision-engineered pipe fitting designed to connect two pipes of different diameters at a 90-degree angle. Constructed from black malleable iron, this elbow offers superior strength, corrosion resistance, and long-term reliability in demanding plumbing and mechanical systems.

This elbow features female iron pipe (FIP) threaded ends on both sides, allowing for secure and leak-resistant connections with standard NPT pipe threads. The reducing configuration (1-1/4" x 1") makes it ideal for transitioning between larger and smaller pipe sizes while maintaining directional flow. It meets ANSI/ASME B1.20.1 threading standards and complies with ASTM A197 and ASME B16.3 specifications for malleable iron fittings.
