ABSTRACT:
An electrofusion coupling for joining together two or more sections of pipe or for joining a section of pipe and a pipework fitting, said coupling comprising: (i) a first part (14) having a first internal diameter at a first end adapted to form a tight sliding fit with a first pipe section and a second internal diameter at a second end, larger than the first; (ii) a second part (14) having a first internal diameter at a first end adapted to form a tight sliding fit with a second pipe section and an outside diameter at a second end adapted to form a tight sliding fit with the second internal diameter of the first part such that the two parts can nest together tightly with an overlapping region; (iii) electrical heating elements (16, 17, 18) and electrical terminal connections being provided in the two parts such that the first part can be used independently of the second part to join a section of pipe to a pipework fitting or the first and second parts can be used in combination to join two adjacent sections of pipe.
