The HDPE Electrofusion Coupler Fitting (also known as an electrofusion straight connector) is designed to join two HDPE pipes in a straight line with high joint strength and long-term sealing performance.
The HDPE Electrofusion Coupler Fitting (also known as an electrofusion straight connector) is designed to join two HDPE pipes in a straight line with high joint strength and long-term sealing performance. Manufactured from premium PE100 high-density polyethylene, it features built-in heating coils that provide uniform heat distribution during the electrofusion welding process.
When energized, the internal resistance wires melt the fitting and pipe surfaces simultaneously, creating a fully integrated, homogeneous joint. This results in a leak-proof, pressure-resistant connection that significantly enhances pipeline safety and reliability.
With outstanding resistance to corrosion, chemicals, UV exposure, and environmental stress cracking, HDPE electrofusion couplers are widely used in demanding pipeline systems where long service life and minimal maintenance are required.
