Legend Valve 313-106NL 1-1/4" T-4200NL Flare x Flare Union

1-1/4" No-Lead Flare Union

The Legend Valve 313-106NL is a T-4200NL flare-by-flare union designed to join two 1-1/4 inch flare fittings in plumbing systems. Constructed from no-lead bronze, it complies with lead-free requirements for potable water installations. The three-part assembly allows straightforward connection and disassembly during maintenance or repair work. California Proposition 65 warnings apply regarding chemicals known to cause cancer and reproductive harm.

Installers needing lead-free flare joints

This union suits plumbers and contractors joining copper or soft tubing with flare ends in water supply lines where no-lead components are mandated. It is not intended for compression, sweat, or threaded connections, so installers using those joining methods should select a different fitting type. The flare-by-flare design requires both mating ends to have formed flare nuts and sleeves before assembly.

1-1/4 inch flare capacity

The fitting accommodates a nominal 1-1/4 inch flare connection on each side, providing a mechanical joint rated for typical residential and light commercial water pressures. Headroom depends on the tubing wall thickness and flare quality rather than the union itself. Systems exceeding standard plumbing pressure ranges or requiring certified gas service should verify compatibility before installation.
