1-1/4" No Lead Bronze Coupling

This coupling joins a flare fitting to a female NPT thread using no lead bronze construction. It carries the Legend Valve 313-026NL part number and T-4105NL model designation. The fitting is supplied new and complies with low lead requirements for potable water systems.

Flare x FNPT Connection Type

The single specification that determines fit is the 1-1/4 inch flare by female NPT thread configuration. This exact combination must match the mating pipe and flare nut on the installation. No other thread standard or diameter will seal correctly with this coupling.

Plumbers and Hydronic Installers

Suited for professionals joining copper flare tubing to threaded iron or brass components in water supply or hydronic heating. Not for installers who need sweat, press, or push-fit ends, or who require a different thread size or gender for the connection.

Questions about this item

What does the 1-1/4 inch size mean when the coupling is installed?

The 1-1/4 inch dimension matches the nominal pipe size for both the flare and female NPT ends, so it connects directly to 1-1/4 inch tubing and threaded pipe without adapters.

How does the flare by FNPT interface affect the pressure rating in service?

The flare-to-FNPT design creates a metal-to-metal seal on the flare side and a tapered thread seal on the FNPT side, both rated for standard residential and commercial water pressures.

What clearance and wrench flats are needed to mount the 313-026NL coupling?

The coupling body provides standard hex wrench flats for a 1-1/4 inch fitting, requiring enough swing room for an adjustable or open-end wrench on each end during assembly.
