1-1/2" Flare x FNPT Coupling

The Legend Valve 313-027NL T-4105NL is a no-lead bronze fitting designed to join a flare connection to a female NPT thread. It serves plumbing installers who need a compliant transition between copper tubing and threaded pipe components.

No-Lead Bronze Construction

The coupling body uses no-lead bronze alloy to meet modern drinking-water safety requirements. The flare end accepts a standard 1-1/2" flare nut while the FNPT end threads directly onto male NPT fittings, allowing straightforward assembly with common wrenches.

Replaces Leaded Brass Transitions

This fitting replaces older leaded brass flare-to-FNPT couplings in potable water lines. The upgrade is justified when local codes or project specifications mandate no-lead materials for health compliance.
