3" x 2-1/2" No Lead Reducing Coupling

This Legend Valve coupling joins a three-inch female NPT pipe to a two-and-a-half-inch female NPT pipe. The cast bronze body contains no lead, making it suitable for potable water systems. It is supplied new and ready for threaded installation.

Installers needing a lead-free transition between

Plumbers working on drinking water lines will find the no-lead bronze construction compliant with safety requirements. The fitting only accepts female NPT threads on both ends, so it cannot connect to male-threaded pipe, press-fit, sweat or push-fit systems without additional adapters. Buyers who need a different thread standard or a larger size reduction must select another part.

FNPT x FNPT threaded connection

The coupling provides female National Pipe Taper threads on both ports, creating a tapered seal when mated with compatible male fittings. This thread type determines whether the part fits the existing piping, so verify the thread specification before purchase.

Which version of the Legend Valve reducing coupling should I choose for a 3-inch to 2-1/2-inch no-lead connection?

The 310-391NL is the specific model for a 3-inch by 2-1/2-inch no-lead cast bronze reducing coupling with FNPT x FNPT threads. Choose this version when you need a direct threaded transition between those two pipe sizes in a potable water system.

What does the Proposition 65 warning on the 310-391NL coupling mean for a real plumbing installation?
