Value Brand 2 1/2 in x 1 in Malleable Iron Reducer Coupling Class 150

Zoro Select Malleable Iron Reducer

This Zoro Select reducer coupling connects a 2 1/2 in pipe to a 1 in pipe using FNPT threads. It is made from malleable iron and rated Class 150 for standard plumbing installations. The fitting meets ASME B 16.3, ASME B 16.4, ASTM A-197 and ASTM A47 standards. It carries FM Approved and UL Listed marks for code compliance.

Capacity and pressure limits

The coupling handles a maximum pressure of 300 psi at 150 Degrees F and saturated steam pressure up to 150 psi. Its temperature range spans -20 Degrees to 366 Degrees F for diverse fluid applications. The Class 150 rating defines its comfortable operating envelope for water, oil and gas lines. It is not suited for systems that exceed these pressure or temperature boundaries.

Build quality and thread implications

Malleable iron construction provides mechanical strength and resistance to cracking under stress. The FNPT threads create a tapered seal that tightens with assembly, requiring thread sealant for leak-free joints. The material and standards suit rigid piping layouts where the fitting remains stationary after installation. It is not designed for frequent disassembly or flexible hose connections.
