Reducer Coupling 1-1/2" x 1-1/4

This malleable iron reducing coupling joins a 1-1/2 inch female NPT pipe to a 1-1/4 inch female NPT pipe. It is suited for plumbing professionals and maintenance crews who need a Class 150 pressure-rated transition. The fitting arrives new and ready for standard threaded assembly.

Class 150 pressure rating

The coupling is rated for Class 150 service, which determines whether it meets the system pressure requirement. Both ends use 11-1/2 threads per inch NPT threads. Verify the operating pressure and temperature against this class before specifying the part.

Threaded installation with sealant

Apply pipe thread sealant or tape to the male threads before engaging the female NPT ports. Tighten to the recommended turns-past-finger-tight to avoid cracking the malleable iron. The most common issue is cross-threading or over-tightening, which can damage the fitting or cause leaks.

Questions about this item

What does the Class 150 rating mean for a reducer coupling installed in a plumbing system?

Class 150 indicates the pressure class for malleable iron fittings, defining the maximum non-shock working pressure at standard temperatures for water, oil, or gas service.

How does the FNPT thread standard affect the connection on this 1-1/2" x 1-1/4" coupling?

FNPT denotes Female National Pipe Taper threads on both ends, requiring male NPT pipes or nipples to create a sealed, tapered joint when tightened with sealant.

What clearance and alignment does this malleable iron reducer need for proper installation?

The coupling joins a 1-1/2 inch male NPT pipe to a 1-1/4 inch male NPT pipe; allow enough space for thread engagement and wrench access on the hexagonal body.
