Stainless steel reducing coupling with female threaded ends

Value Brand

Value Brand 2" x 1-1/2" FNPT 304 SS Reducing Coupling

SKU CH-RGAW-XZRHK

Stainless steel 304 reducing coupling joins 2-inch and 1-1/2-inch FNPT threaded pipe at up to 300 psi

  • 304 stainless steel resists corrosion in plumbing systems
  • Class 150 rating handles 300 psi maximum operating pressure
  • Schedule 40 compatibility fits standard pipe dimensions
  • Female NPT threads on both ends enable secure connections
  • Reduces 2 inch to 1-1/2 inch pipe sizes

Value Brand Reducing Coupling

This Value Brand reducing coupling connects a two-inch female NPT thread to a one-and-a-half-inch female NPT thread. It is made from 304 stainless steel for corrosion resistance in fluid-handling systems. The fitting is rated for a maximum operating pressure of 300 psi. It suits installers joining pipes of different diameters in a straight line.

For Schedule 40 Pipe Installations

This coupling is built for Schedule 40 pipe and carries a Class 150 pressure rating. It works for plumbing, hydraulic or pneumatic lines that use National Pipe Taper threads. Builders who need a compression, flared or welded connection will not be able to use this threaded fitting. It also does not suit applications that require a male-threaded end or a different material grade.

300 psi Maximum Operating Pressure

The 300 psi pressure limit is the critical figure for specifying this part. Systems that run above this pressure must choose a higher-rated fitting to avoid failure. Verify that the service pressure stays within this rating before installing the coupling. The Class 150 designation aligns with this pressure ceiling for Schedule 40 piping.

Questions about this item

Will this 2 in x 1 1/2 in reducing coupling fit Schedule 40 pipe with 11.5 threads per inch?

Yes, both the 2 in and 1 1/2 in ends are Female NPT threaded at 11.5 TPI and rated for Schedule 40 pipe.

Do I need to use thread sealant or tape when installing this 304 stainless steel FNPT reducing coupling?

Apply PTFE tape or pipe dope on the male threads before tightening; the stainless threads can gall if assembled dry.

How often should I inspect or replace this Class 150 stainless steel reducing coupling in a 300 psi system?

Inspect annually for leaks or corrosion; replace if threads show deformation or if pressure testing exceeds the 300 psi rating.
