Legend Valve 462-627NL PEX Adapter

The Legend Valve 462-627NL is a no-lead forged brass adapter connecting 1-1/2 inch cold expansion PEX tubing to a sweat fitting. It serves installers working on potable water systems in residential or RV plumbing projects. The component meets California Proposition 65 disclosure requirements for listed chemicals.

Verify PEX Type and Fitting Compatibility

Confirm the existing tubing uses the F1960 cold expansion method rather than a crimp or clamp system before ordering. The sweat end requires copper pipe prepared for soldering with appropriate flux and alloy. No threading or press-tool connection is present on either port.

Replaces Threaded or Crimp Transition Fittings

This adapter replaces separate threaded couplings or crimp-style transition pieces when joining PEX to copper. The jump is worth it when a direct, lead-free forged brass joint reduces potential leak paths and simplifies the solder-to-PEX transition in new installations.
