Dielectric Union for 1-1/4" Pipe

The Legend Valve 301-306 T-572 dielectric union connects dissimilar metal piping while preventing galvanic corrosion. It is intended for plumbers and maintenance technicians who need a reliable transition fitting in potable water or hydronic systems. The component isolates copper from steel or iron to extend pipe life.

Brass and Steel Construction with Insulating Gasket

The union body combines brass and steel sections separated by a non-conductive gasket that breaks the electrical path between metals. Standard NPT threads allow direct assembly onto 1-1/4 inch pipe without special tools. The design supports routine disassembly for service or inspection.

Sealed Joint Rated for Typical Service Pressure

The gasket material resists hot water temperatures common in residential and light commercial installations. Once tightened, the joint maintains a leak-free seal under normal pressure cycles. No external power or active components are involved, so noise and energy draw are not factors.
