A range of Doughty couplers for fixing pipe to pipe, and half couplers for attaching fixings to pipe. Couplers are compatible with tube diameters from 48-51mm. The greater contact area of the extrusion results in less damage than typical pressed-steel types, to give great strength, with less weight.
Three types of pipe to pipe couplers are available, each constructed of two connected assemblies. Swivel versions rotate about the joining bolt whilst parallel couplers and 90% couplers connect two pipes at a fixed angle.
Five types of half couplers are available, each with an M12 bolt hole for attaching fixings.
