HDPE Electrofusion Fittings are high-density polyethylene pipe fittings that can be melted by the temperature generated by an electric current for joining purposes. These fittings are mainly used in polyethylene piping systems to connect different grades of PE pipe and different wall thicknesses of PE pipe by means of electrofusion. The color of the electrofusion fittings has no effect on compatibility, and the reliability of the connection is high. The strength of the connection needs to be higher than the strength of the pipe itself to ensure that there is no leakage of the medium during the connection process.
