Lead-Free Bronze Compression Union

The Legend Valve 313-156NL is a no-lead bronze union designed for copper tube size compression connections. It joins two 1-1/4 inch CTS lines in residential and commercial plumbing installations. The fitting meets no-lead requirements for potable water systems. It is supplied new for professional and DIY use.

Proposition 65 Chemical Notice

This product carries a California Proposition 65 warning for exposure to chemicals known to cause cancer and reproductive harm. The notice applies to the bronze alloy used in the fitting body. Installers should follow standard safety practices when handling and soldering near the component. The warning does not prohibit sale or installation in California.

Replaces Leaded Brass Unions

This union upgrades older leaded brass compression fittings in potable water lines. The jump is required when local codes mandate no-lead materials for drinking water supply. It is not suited for flare, press, or threaded pipe connections without appropriate adapters. Buyers needing a different end configuration or tube size must select an alternative fitting.
