1/2" Copper-to-FIP union for potable water

This Legend Valve 302-316NL union joins 1/2-inch copper sweat pipe to a female NPT thread in residential and light-commercial plumbing. The no-lead brass body meets low-lead requirements for drinking-water systems. California Proposition 65 warnings apply because the brass contains chemicals identified by the state as carcinogenic and reproductive hazards. Installers should verify local code acceptance before use.

No-lead brass withstands continuous pressure

The large-body design distributes stress across a generous brass cross-section so the joint remains tight during daily pressure fluctuations and hot-water temperature swings. No-lead alloy resists dezincification and corrosion in chlorinated municipal supplies. Sweat and threaded ends allow a permanent copper connection on one side and a serviceable threaded joint on the other without introducing dissimilar-metal corrosion at the interface.

Replaces standard leaded-brass unions in lead-free

This fitting upgrades older 1/2-inch sweat-by-FIP unions when a project must comply with current no-lead statutes or when the specifier requires a California Proposition 65 disclosed component. The jump is worth it on new potable-water rough-ins, remodel tie-ins and any repair where the authority having jurisdiction mandates certified no-lead brass. It does not suit gas piping, high-purity process lines or applications that demand a dielectric union.

Questions about this item

How much heat does the 1/2" Copper x FIP Union generate during continuous water flow?

The union is a passive brass fitting with no moving parts or electrical components, so it produces no measurable heat during normal plumbing operation.

What existing plumbing must I already have to install this 1/2" sweat-to-FNPT union?

You need a 1/2-inch copper pipe ready for sweat soldering and a matching 1/2-inch female NPT threaded connection on the adjoining fixture or valve.

Will the no-lead brass body of this 302-316NL union corrode when joined to older standard-brass valves?

The no-lead brass alloy is compatible with traditional brass; galvanic corrosion risk is negligible in potable-water systems with similar copper-based alloys.
