PE/Brass Electrofusion Transition Coupler with Union SDR11

  Data Sheet |   Product Range | Instructional Video

The Georg Fischer ELGEF Plus electrofusion transition coupler with brass female thread and integrated union end is engineered for dependable, demountable transitions between polyethylene (PE100/PE80) pipe networks and metallic piping components, valves, or instrumentation. Rated for SDR11 systems operating at up to 16 bar for water and 10 bar for combustible gas, this fitting provides a permanent electrofusion joint on the polyethylene side paired with a detachable, threaded brass union interface on the utility side. Supplied as a complete factory-tested kit with a precision flat gasket, it streamlines on-site assembly and future maintenance in municipal distribution, plant utility piping, and demanding industrial installations.

Manufactured from high-grade virgin PE100 resin and corrosion-resistant brass, the electrofusion socket features embedded heating coils, standard 4 mm connector pins, and dynamic limited-path fusion indicators that provide visual confirmation of completed welding cycles. Smaller diameter variants integrate Georg Fischer pipe fixation mechanisms that clamp the pipe in place without external alignment tools, eliminating stress during fusion and cooling. The union joint allows mechanical decoupling without cutting the PE pipeline, protecting pipe integrity during routine equipment replacement, pump servicing, or meter recalibration. With an estimated operating lifespan of 100 years, the fitting withstands harsh soil conditions, aggressive water chemistry, and ambient thermal fluctuations.

Compliant with European quality standards EN 12201-3 for potable water distribution and EN 1555-3 for natural gas networks, this transition coupler carries leading international hygienic and safety certifications including DVGW, ACS, and KIWA. Embedded barcode technology ensures full Track & Trace capability across modern electrofusion control boxes, recording welding voltage, ambient temperature compensation, and production parameters for certified quality assurance. As an authorised Georg Fischer distributor, BigWeld supplies the full range of ELGEF Plus SDR11 electrofusion transition fittings to industrial contractors and utility engineers across Europe.
