Black Reducing Coupling for plumbing systems

This Legend Valve 350-557 coupling joins a 3-inch female NPT pipe to a 1-1/4-inch female NPT pipe. The black finish suits standard plumbing installations. It is a new component supplied directly by the manufacturer.

Suited for installers reducing pipe diameter

Plumbers and maintenance teams use this fitting to transition between different pipe sizes in water or gas lines. It is not for buyers who need a straight coupling of identical diameters or a fitting with a different thread standard such as BSP.

Withstands continuous system pressure

The coupling maintains a sealed joint under sustained operating pressure in residential and commercial piping. It does not degrade during prolonged exposure to the conveyed fluid. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

What size pipes do I need to connect to the 3 x 1-1/4 FNPT threads?

You need a 3 inch male NPT pipe on one side and a 1-1/4 inch male NPT pipe on the other to match the female threads.

Will this black reducing coupling join older galvanised pipe threads without leaks?

Yes, the FNPT tapered threads are designed to seal with standard NPT pipe threads of the same nominal sizes.

How can I confirm the 350-557 coupling is sealed correctly after installation?

Pressurise the system and check both thread joints for any water seepage; a dry joint indicates a proper seal.
