Legend Valve 2" Copper Union

This 2-inch sweat-to-male-union fitting joins copper pipe to male-threaded components in potable-water systems. The no-lead brass body meets low-lead requirements for drinking-water installations. It suits plumbers and contractors working on residential or light-commercial bathware projects.

Replaces Standard Lead Brass Unions

The no-lead alloy replaces older leaded-brass unions where current codes prohibit lead content. The upgrade is worth it when the authority having jurisdiction enforces Proposition 65 or equivalent no-lead standards. It does not serve applications that require female-threaded or press-connect ends.

Easy Sweat Installation

A plumber solders the sweat end to copper tubing and threads the male NPT side into the mating fitting using standard flux, solder and pipe dope. Common issues include overheating the joint, which can damage the seat, and insufficient thread sealant, which causes leaks at the male connection.
