Dielectric unions are essential components designed to safeguard your piping system from accelerated corrosion and deterioration caused by galvanic and stray currents, especially when pipes are constructed from dissimilar metals. This innovative solution comprises a union nut, two tail-pieces, a gasket, and a sleeve meticulously crafted to isolate the tail-pieces, effectively preventing the occurrence of electric currents.
