Durafuse Electrofusion and Butt-fusion.

Durafuse Electrofusion and Butt-fusion

The DuraFuse brand of electrofusion and butt-weld fittings are offered by GPS, part of Aliaxis, the world’s largest manufacturer and supplier of quality pipeline solutions. As global specialists in polyethylene (PE) systems for the transportation of gas, water and industrial fluids, Durafuse have over 50 years experience developing plastic fittings for low and medium pressure applications.

With a comprehensive choice of cost effective pipeline products and associated tooling, conforming to the highest British, European and International standards, Durafuse provide you with reliable, total peace of mind solutions.


Why choose a polyethylene system?

When polyethylene is used within pipe systems it offers a unique set of qualities that can save valuable time and money and ensure long-term reliability and efficiency, compared to traditional materials. These properties include:

  • Light-weight
  • Non-corrodible
  • 50 year life span
  • Flexibility
  • Smooth internal bore
  • Excellent chemical resistance
  • Good insulation characteristics



Electrofusion Fittings

In order to meet the needs of our customers our DuraFuse electrofusion fittings are offered in PE100 black, PE100 blue and PE80 yellow. This allows you to choose products that meet your own system specifications and standards. We offer a full range of fittings available with 4.7mm terminal pins in sizes 20mm up to 400mm. Most fittings are supplied for 39.5V operation and are available in SDR11 and are therefore suitable for applications up to 16 bar for water and 10 bar for gas. We currently have larger fittings in development; please contact us for further information.
