Lead-Free Bronze Union

This Legend Valve 313-256NL union connects 3/4 inch IPS pack joints to 1 inch CTS pack joints using no-lead bronze construction. It meets California Proposition 65 disclosure requirements for chemical content. The fitting serves residential and commercial plumbing systems requiring a direct transition between these two pipe standards.

Pack Joint Assembly

The union installs by tightening the pack joint nuts onto prepared pipe ends; no soldering, threading or specialised crimp tools are required. Leaks typically occur when pipe ends are not cut square, are insufficiently deburred or are not fully seated before the nuts are torqued. Over-tightening can deform the gasket and compromise the seal.

Pipe Compatibility Check

Verify that the existing piping matches 3/4 inch IPS on one side and 1 inch CTS on the other before ordering. Confirm the pipe material is approved for pack joint connections and that local code permits no-lead bronze fittings in the intended application. Ensure adequate access exists to tighten both union nuts.

Questions about this item

How do I verify the Legend Valve 313-256NL coupling is working after installation?

Pressurise the line and inspect the pack-joint seals at both the IPS and CTS ends for leaks; a dry joint under normal operating pressure shows the union is seated correctly.

What comes with the 313-256NL fitting and what must I supply?

The box contains the no-lead bronze union marked T-4325NL; you must provide compatible IPS and CTS pipe, pack-joint gaskets or compression rings, and any thread sealant required by local code.

Which Legend Valve coupling version should I choose for a 3/4 to 1 inch transition?

Select the 313-256NL model — it is the 3/4" x 1" T-4325NL no-lead bronze pack-joint IPS by pack-joint CTS union designed for that exact size change.
