Product Identity

The Legend Valve 301-305 is a 1 inch T-572 dielectric union designed for plumbing systems. It separates dissimilar metals to prevent galvanic corrosion in water lines. This new fitting suits installers and maintenance teams working on residential or commercial pipework.

Critical Specification

The T-572 model designation identifies the exact union configuration required for compatibility. Matching this model number to the system design is the single factor that decides whether this is the correct part for the joint.

Operational Characteristics

As a passive mechanical fitting, the union draws no power and produces no noise during normal operation. Thermal performance depends on the fluid temperature and pipe insulation rather than the fitting itself. California Proposition 65 notices apply regarding contained chemicals.

Questions about this item

What does the 1 inch size mean for pipe compatibility?

The 1 inch designation matches standard nominal pipe thread dimensions so it threads onto 1 inch NPT connections without adapters.

How does the dielectric union isolate dissimilar metals?

An internal insulating sleeve separates the brass and steel halves to break the electrical path and slow galvanic corrosion.

What clearance is needed to install the T-572 union?

Allow enough straight pipe length for the union body plus wrench flats on both ends to tighten the joints.
