Legend Valve 313-252NL PEP x CTS Coupling

This new brass coupling connects 1-inch PEP pipe to 3/4-inch CTS tubing using pack-joint ends. The T-4325NL no-lead bronze body meets Proposition 65 disclosure requirements. It suits residential and light-commercial water lines. Installers get a straight union without soldering.

Suits PEP-to-CTS transitions; not for other combos

Plumbers joining 1-inch PEP to 3/4-inch CTS pipe will find the correct ends here. The pack-joint design avoids threading or sweating copper. Buyers needing different pipe materials, diameters, or thread types must select another fitting. This unit does not adapt to those configurations.

No-lead bronze T-4325NL body

The fitting uses a no-lead bronze alloy designated T-4325NL to satisfy California Proposition 65 limits. This material choice is the deciding factor for potable-water compliance. Confirm local code acceptance before purchase. No other alloy or leaded variant is supplied.

Questions about this item

What pipe sizes must I already have for the 1 x 3/4 PEP x CTS T4325 coupling to connect?

You need one 1 inch PEP pipe end and one 3/4 inch CTS pipe end; the union joins those two sizes directly.

Will the no-lead bronze union work with older leaded-bronze fittings already in the system?

Yes, the T4325NL no-lead bronze threads seal against existing leaded-bronze pack-joint fittings without galvanic issues.

How can I confirm the 313-252NL coupling is seated and leak-free after assembly?

Pressurise the line and inspect both pack-joint nuts; no water should escape from the gasket seats when the system is at working pressure.
