PE/Polyethylene Electro Heating Fusion Sleeve for Directly Buried Pre-Insulated Pipe
Our PE/Polyethylene Electro Heating Fusion Sleeve is a specialized
HDPE fitting designed for the reliable and efficient joining of
directly buried pre-insulated pipes. The sleeve features a pre-cut
HDPE sheet embedded with a high-temperature resistant nichrome
heating mesh, enabling robust, leak-proof, and corrosion-resistant
joints through electro-fusion welding.
