Electrofusion Control Units

Our ECU is an automatic electrofusion welding unit, designed to join bar coded PE and PP pressure fittings with a range of 8v to 48v. It has been designed to be used simply and its fast user interface allows fittings to be welded reliably.

The ECU is designed for UK projects and as such does not limit the user by "brand specific fittings use only" - many cheaper boxes particularly from Scandinavia are chipped to only work with a sole make of fitting. The GG ECU is compatible with all leading brands of UK and European fittings offering peace of mind when sourcing EF fittings from a variety of sources. Visit our website for more info.
