Brass Coupling for Plumbing Systems

This straight coupling connects two sections of 1 1/4 inch female NPT pipe. It is built from red brass rated to Class 125 for standard water and air lines. The fitting suits installers who need a durable, pressure-rated joint in residential or light commercial work. It is not for buyers who require a reducing coupling to join different pipe diameters.

Maximum Operating Pressure 200 psi

The single specification that decides fit is the 200 psi maximum operating pressure at Class 125. Verify that your system design pressure stays within this limit before installation. The female NPT threads on both ends accept standard tapered male pipe threads. This coupling cannot be used where a higher pressure rating or a different thread standard is specified.

California Proposition 65 Compliance Notice

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The brass construction handles normal thermal cycling in hot and cold water service without deformation. No moving parts or seals are present, so the fitting adds no noise or vibration to the line. Power draw is not applicable for this passive component.

Questions about this item

What does the 200 psi rating mean when the coupling is installed in a plumbing system?

The coupling is rated for a maximum operating pressure of 200 psi, so it will hold that pressure in a correctly assembled threaded joint without leaking.

What does the Class 125 designation limit in everyday use?

Class 125 indicates the fitting is manufactured to a standard pressure class for 125 lb flanges, which aligns with the 200 psi maximum operating pressure for water, oil, or gas service.

What thread type and size are needed to connect this coupling to existing pipe?

Both ends have 1 1/4 inch female NPT threads, so you need male NPT pipe or nipples of the same size to screw into each side.
