Unions

Unions

A union, similar to a coupling, allows the convenient disconnection of pipes for maintenance or fixture replacement. Although a coupling requires solvent welding, soldering or rotation (threaded couplings), a union allows easy connection and disconnection. It consists of three parts: a nut, a female end and a male end. When the female and male ends are joined, the nut seals the joint. Unions are a type of flange connector.

Dielectric unions, with dielectric insulation, separate dissimilar metals (such as copper and galvanized steel) to prevent galvanic corrosion. When two dissimilar metals are in contact with an electrically-conductive solution (tap water is conductive), they form a battery generating a voltage by electrolysis. When the metals are in direct contact with each other, the electric current from one to the other moves ions from one to the other; this dissolves one metal, depositing it on the other. A dielectric union breaks the electrical path with a plastic liner between its halves, limiting galvanic corrosion. Rotary unions allow rotation of one of the joined parts.
