Legend Valve 301-325NL 1" T-573 No Lead Dielectric Union

1-Inch T-573NL Dielectric Union

The Legend Valve 301-325NL is a 1-inch T-573NL dielectric union designed for plumbing systems requiring dissimilar metal connections. It prevents galvanic corrosion between different pipe materials in residential and commercial installations. Professional plumbers and maintenance technicians use this fitting to ensure system longevity. The no-lead construction meets current safety standards for potable water applications.

Brass Body With No-Lead Certification

The brass body incorporates a dielectric insulator that electrically separates connected pipes to stop electrolytic corrosion. This union installs with standard pipe wrenches using conventional threading methods familiar to any pipefitter. The no-lead designation confirms compliance with regulations for drinking water systems. California Proposition 65 warnings indicate the presence of chemicals known to cause cancer and reproductive harm.

1-Inch Nominal Pipe Size Connection

This union accommodates 1-inch nominal pipe size connections for standard plumbing configurations. The T-573NL model designation identifies the specific dielectric union pattern and no-lead material specification. Buyers needing other pipe diameters or non-dielectric coupling types must select alternative fittings. Verify system pressure and temperature requirements against manufacturer documentation before installation.
