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

This malleable iron reducing coupling joins a 2 inch female NPT pipe to a 1-1/2 inch female NPT pipe. It is rated for Class 150 service and uses 11-1/2 threads per inch on both ends. The fitting suits plumbing systems that require a step-down in pipe diameter.

Capacity and pressure rating

Class 150 designation indicates the pressure class this coupling is manufactured to meet. It handles standard residential and light commercial water, air and oil lines within that rating. The fitting is not intended for high-pressure hydraulic or steam systems that exceed Class 150 limits.

NPT thread interface

Both ports use National Pipe Taper threads with 11-1/2 threads per inch. The taper creates a seal when tightened, but proper thread sealant or tape is required for leak-free joints. The coupling cannot connect to straight-thread or metric pipe standards without an adapter.

Questions about this item

Will this reducer coupling connect my existing 2-inch NPT pipe to a 1-1/2-inch NPT line?

Yes, it joins a 2-inch female NPT thread to a 1-1/2-inch female NPT thread, both at 11-1/2 threads per inch.

How can I verify the coupling is rated for my system pressure after installation?

The Class 150 malleable iron body is designed for standard pressure service; check for leaks at the threaded joints once assembled.

Does the package include pipe sealant or do I need to buy thread tape separately?

The box contains only the reducer coupling; thread sealant or tape must be purchased separately for the NPT connections.
