PUHUI offers a full range of HDPE Electrofusion Fittings from 20mm to 1600mm, available in SDR9, SDR11, SDR17, and SDR26 pressure classes. These fittings are designed for secure, leak-free jointing in water and gas distribution, irrigation systems, mining operations, and landfill applications.

Our HDPE electrofusion fittings are seamlessly molded to minimize potential leak points and are manufactured using virgin PPI-listed PE4710 and PE100 resins. All fittings are designed and tested to meet or exceed EN 12201, EN 1555, ISO 4427, ISO 4437, and ASTM D3350 standards. Production is controlled under a strict ISO 9001–certified quality management system, ensuring consistent performance and reliability.

HDPE Electrofusion Fittings – Installation Procedure

» Cut the pipe squarely using a suitable pipe cutter or saw, ensuring a clean and perpendicular cut.

» Mark the insertion depth on the pipe by measuring the fitting socket depth and identifying the area to be peeled.

» Peel the pipe surface at the marked insertion depth using a rotary peeler to remove the oxidized layer.

» Clean the peeled pipe surface and the internal surface of the fitting using approved welding wipes.

» Insert the pipe into the fitting until it reaches the internal stop, ensuring a proper tight fit.

» Align and clamp the pipe and fitting securely using an alignment clamp to prevent movement during fusion.

» Connect the electrofusion terminal cables to the fitting terminals and scan or manually input the fusion parameters (voltage and time).

» Fuse the joint using the electrofusion machine for the preset fusion time. Fusion indicators (pins) will rise to confirm completion.
