1" No-Lead Bronze Union

The Legend Valve 313-257NL is a 1-inch union coupling designed for potable water plumbing installations. It connects IPS pack-joint pipe to CTS pack-joint pipe using a no-lead bronze body that meets low-lead requirements. The T-4325NL model suits contractors and maintenance crews joining dissimilar pipe types in residential or commercial systems.

Pack-Joint IPS to CTS Transition

This fitting joins iron-pipe-size pack-joint connections to copper-tube-size pack-joint connections without soldering or threading. The no-lead bronze construction resists dezincification and complies with safe-drinking-water standards. The union design allows the joint to be disassembled for service or reconfiguration while maintaining a reliable seal on both pipe types.

Questions about this item

What pipe sizes does the 1" T-4325NL No Lead Bronze Pack Joint (IPS) x Pack Joint (CTS) Union connect?

It joins a 1-inch IPS pack-joint end to a 1-inch CTS pack-joint end, allowing a direct transition between the two pipe standards.

What physical clearance does the union body need for installation?

The union body requires enough space to slide the pack-joint nuts over the pipe ends and tighten them, so allow room for the nut diameter and wrench access on both sides.

How is the union assembled, and which step is often missed?

Slide each pack-joint nut and gasket onto the pipe, insert the pipe into the union ends, then tighten both nuts; the step often missed is seating the gasket fully before tightening.
