Reducing Coupling 1-1/2" x 1/2" FNPT

This malleable iron reducing coupling connects a 1-1/2 inch female NPT pipe to a 1/2 inch female NPT pipe. It is rated for Class 150 service and suits plumbing installations that require a step-down in pipe diameter. The fitting is new and supplied under the ZORO SELECT brand.

Class 150 Malleable Iron Construction

The Class 150 pressure rating defines the maximum working pressure for this fitting at standard temperatures. It replaces or upgrades from lighter-duty fittings that cannot meet the same pressure class. The jump is worth it when the system design calls for a malleable iron coupling rated to this specific class.

Threaded Connection Capacity

The coupling provides 11-1/2 threads per inch on the larger end and 14 threads per inch on the smaller end, both to NPT standards. It comfortably handles the transition between the two pipe sizes within its rated class. It runs out when the application demands a higher pressure class or a different thread configuration.
