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.

Questions about this item
Will the 200 psi maximum operating pressure limit flow before the brass threads wear?
The 200 psi maximum operating pressure is the first limit reached under sustained use; brass threads typically outlast the pressure rating when installed correctly.
Does the brass coupling generate noticeable heat or noise when pressurised continuously?
Brass conducts heat well, so the body stays near fluid temperature and produces no audible noise under steady pressure.
Which mating fittings must I already have to connect this 1-1/2" FNPT to 1-1/4" FNPT coupling?
You need a 1-1/2" MNPT fitting on one side and a 1-1/4" MNPT fitting on the other, plus thread sealant rated for 200 psi service.
