2" No-Lead Dielectric Union Valve

The Legend Valve 301-108NL is a 2-inch dielectric union valve with FNPT by sweat connections. It is designed for plumbing systems that require separation of dissimilar metals to prevent galvanic corrosion. The T571 no-lead construction meets requirements for potable water installations. This valve suits professional installers and maintenance crews working on commercial or residential piping.

California Proposition 65 Compliance

This product carries California Proposition 65 warnings for chemicals known to cause cancer and birth defects or other reproductive harm. The notices are regulatory labels attached to the item by the manufacturer. They do not describe thermal behaviour, acoustic output or electrical power draw because the valve is a passive mechanical component with no moving electrical parts.

FNPT by Sweat Connection Type

The single specification that decides fitment is the 2-inch FNPT by sweat end configuration. The female thread mates with standard male pipe threads while the sweat end accepts copper tubing for brazed joints. Verify that both the thread standard and the tube diameter match the existing piping before purchase.

Questions about this item

How do I install the 2" FNPT x Sweat dielectric union and what step is often missed?

Thread the FNPT end onto the pipe using appropriate sealant, then sweat the copper tailpiece; the step often missed is removing the internal dielectric sleeve before heating so the gasket is not damaged.

What maintenance or replacement will the T-571NL dielectric union need over time?

Inspect the dielectric gasket annually for cracking or compression set and replace it if leakage appears; the brass and copper bodies do not require scheduled replacement.

What limit appears first on the 301-108NL union under sustained hot-water use?

The dielectric gasket reaches its temperature and pressure rating before the brass or copper components, so gasket degradation is the first limiting factor.
