The Spider 125 makes polypropylene fittings and pipe fusion of up to 125 mm incredibly simple, once the correct socket fusion kits have been chosen. The unit is designed to be lightweight, and the use of it involves a single person with expertise in aligning, heating, fusing, and pipe cooling, which means the rest of the team can concentrate on more essential tasks. Being that the machine is compact and lightweight, Spider 125 is able to perform fast socket fusions in multiple ways and it can work well in confined spaces.
