Lead-Free Bronze Coupling for Potable Water

The Legend Valve 313-606NL is a no-lead bronze coupling designed to join a 1-inch flare fitting to a 5/8-inch extra-strong pipe end. It provides a secure, pressure-tight connection in plumbing systems that must meet lead-free requirements for drinking water. The T-4110NL body resists dezincification and corrosion in typical residential and light commercial installations. This fitting is supplied new and ready for immediate use.

Installers Meeting No-Lead Codes

This coupling suits plumbers and maintenance teams working on potable water lines where lead-free components are mandated by local codes or California Proposition 65 compliance. It is not intended for gas distribution, high-temperature hydronic heating, or applications requiring a sweat, press, or threaded joint instead of a flare-to-extra-strong transition. Buyers needing a different end connection or a larger bore should select an alternative fitting style.

The Deciding Specification Is

The single detail that determines fit is the 1-inch flare by 5/8-inch extra-strong end configuration. Only systems using exactly this combination of flare nut and extra-strong pipe diameter will accept the coupling without adapters. Verify the pipe schedule and flare standard before ordering to avoid mismatched threads or sealing faces.

Questions about this item

What pipe sizes does the 1 x 5/8 inch T-4110NL flare by extra strong coupling connect?

The coupling joins a 1 inch flare connection to a 5/8 inch extra strong pipe end for a secure transition.

How is the flare end of the 313-606NL coupling installed without causing leaks?

Tighten the flare nut onto the mating flare fitting until metal-to-metal contact seats the seal; do not apply thread sealant to the flare face.

When should the no lead bronze coupling be inspected or replaced in a potable water system?

Inspect annually for corrosion or drips; replace if the flare seat shows pitting or if water testing reveals lead above the Proposition 65 threshold.
