Value Brand 1-1/2" x 1-1/4" FNPT Brass Coupling

Brass Coupling for Female NPT Pipe Connections

This brass coupling joins a 1-1/2 inch female NPT thread to a 1-1/4 inch female NPT thread. It suits plumbing installers and maintenance crews who need to transition between these two pipe sizes in water, air or inert gas lines. The fitting is rated for 200 psi maximum operating pressure. It is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Threaded Fitting That Requires Male NPT Counterparts

Each end accepts a male NPT pipe nipple, adapter or component, so the installer must provide matching male threads and suitable thread sealant. The coupling itself adds no moving parts and frees the assembler from sourcing a custom reducer. No special tools beyond standard pipe wrenches are needed to make the joint.

Solid Brass Body Holds Pressure Continuously

The all brass construction resists corrosion and maintains its 200 psi rating under sustained system pressure without the creep seen in plastic alternatives. Thread engagement distributes mechanical load evenly across the joint during long term service. The fitting contains no seals or elastomers that can degrade over time.
