Product Description

A polyethylene electrofusion equal coupling is a key fitting used to join two PE pipes of the same diameter. The inner wall of the fitting contains embedded spiral heating wires, with electrode terminals positioned at both ends. When connected to a professional electrofusion control unit, electric current heats the embedded wires, causing the contact surfaces between the fitting and the pipes to melt and fuse together, forming a strong, reliable, and leak-proof joint within the piping system.
