Mec 1/2 In. Mnpt X 3/8 In. Male Flare, Brass Space-Saver Dielectric Union

Product Description

The ME690 series dielectric unions are intended to isolate metallic piping from sources of electrical current and to help prevent galvanic corrosion. The ME690 dielectric union would typically be installed at the ASME tank directly downstream of the first stage regulator but prior to underground piping and/or at the inlet of the second stage regulator above ground at the dwelling there by protecting the underground metallic piping from corrosion and electrical current. 1/2 in.
