Brass Dielectric Unions

Brass Dielectric Union – Dissimilar Metal Transition Fitting

A Brass Dielectric Union is a plumbing fitting used to join two different types of metal pipes—most commonly copper and galvanized steel—while preventing galvanic corrosion caused by direct metal-to-metal contact.

Key Features:

Dissimilar Metal Connection: Safely joins copper to galvanized steel piping systems.
Corrosion Prevention: Uses an internal plastic or rubber insulator to break electrical continuity between metals.
Dielectric Isolation: Prevents galvanic reaction that leads to rust, erosion, and premature leaks.
Durable Materials: Brass construction for strength and long-term reliability.
Threaded Union Design: Allows easy assembly and disassembly for maintenance.
Water System Use: Common in potable water, irrigation, and plumbing systems.
Long-Term Protection: Extends service life of mixed-metal piping installations.

Reliable and essential for preventing corrosion when connecting different metal piping systems.
