3/4 inch bronze union for potable water systems

This no-lead cast bronze union connects two female NPT threads in plumbing installations. It is built for use with drinking water where lead-free materials are required by code. The 310-144NL model suits residential and light commercial pipework.

Cast bronze body with threaded ends

The union uses FNPT x FNPT connections so pipes can be joined or separated without cutting. Bronze construction resists corrosion in water supply lines. California Proposition 65 notices apply because the alloy contains listed chemicals.

Replaces leaded unions in code-mandated upgrades

Swap out older brass or bronze fittings when local regulations demand no-lead components. The jump is worth it during repipes, fixture replacements or any work inspected for lead compliance. Not for buyers who need a different thread size or a solder-end connection.

Questions about this item

What thread standard does the 310-144NL union use for its FNPT connections?

The union uses FNPT tapered pipe threads on both ends to create a pressure-tight seal without a gasket.

What pipe size and material does this bronze union accommodate?

It fits 3/4 inch nominal pipe and joins copper, steel or plastic piping rated for the same pressure class.

How is the no-lead bronze union installed and which step is often missed?

Apply thread sealant to the male threads, tighten each tailpiece to the pipe, then draw the union nut up against the seat; the step often missed is lubricating the seat face before final tightening.
