Legend Valve 310-143NL bronze union

This 1/2 inch no-lead bronze union connects two female NPT threads in potable water systems. It serves plumbers and maintenance crews who need a separable joint without soldering. The union design allows quick disassembly for repairs or equipment changes. It meets no-lead requirements for safe drinking water installations.

Sustained pressure performance

The cast bronze body resists corrosion and mineral buildup during continuous water exposure. Threaded joints maintain a reliable seal under normal supply pressure without loosening over time. No-lead construction prevents contaminant leaching throughout the service life. The union nut permits repeated break-and-make cycles without degrading the sealing faces.

Build quality and daily use

Cast bronze provides mechanical strength for standard residential and light commercial plumbing. FNPT x FNPT threads accept common pipe nipples and fittings without adapters. The union nut rotates freely for alignment in tight spaces. California Proposition 65 warnings apply due to regulated substances in the alloy.

Questions about this item

Does the 1/2 inch bronze union generate any heat or noise when water runs through it all day?

The coupling is a passive bronze fitting with no moving parts, so it produces no noise or heat during continuous water flow.

What pipe threads must I already have for the 310-143NL to connect properly?

Both ends use 1/2 inch FNPT threads, so you need matching male NPT pipe or adapters on each side.

Will the no-lead bronze union work with older leaded-bronze or brass fittings I plan to keep?

Yes, the FNPT threads are standard, so it threads directly onto existing leaded-bronze or brass nipples without galvanic issues.
