Dielectric Unions

Dielectric Unions

Use these dielectric unions (DEUs) to help prevent galvanic corrosion (also known as bimetallic corrosion) when connecting pipes of dissimilar metals, which can cause pipes to corrode and fail. They have a nonconductive gasket that creates an electrical barrier between two pipes of noncompatible metals. Unions have a hex-shaped nut that can be unscrewed with a standard wrench to install, remove, or maintain pipes with less disruption to your system than threaded fittings. These fittings are often used in pipe systems carrying steam, gas, and hot water that are required to meet specific building code requirements.
