An electrofusion coupler fitting / HDPE coupling Fitting is used to join two lengths of poly pipe in a straight line. HDPE coupling Fittings are also used to join a long spigot fitting to a piece of pipe. With a size range from 20 mm to 800 mm, electrofusion coupling fittings come in SDR 11 (which also suits SDR 13.6 & SDR 17). SDR 11 electrofusion couplers are rated to PN16 water and 1000 kPa gas, and SDR 17 electrofusion couplers are rated to PN10 water and PN6 gas.
Electrofusion coupler fittings are made from PE100 material with a precisely moulded energizing coil of wire, ensuring uniform melting for a strong electrofusion joint and the minimisation of welding and cooling times. Electrofusion couplings are suitable for use for HDPE Pipe, and welded with an electrofusion pressure welder. Electrofusion coupling joiners may also be known as electrofusion joiners, HDPE coupling Fitting, electrofusion socket fittings or EF pipe joiners.
