Abstract

A coupling assembly for plastic pipes including a nut, a body, a grip-ring, and a seal. The nut can engage the body through appropriate threads and includes a hooked projection having a sloping surface adapted to abut against and provide a force on a corresponding surface of the grip ring within the body. A pipe is inserted through the nut, grip-ring, and seal into the body. Tightening of the nut causes its sloped surface to engage and the grip ring to be forced both radially and longitudinally. Radial compression results in the grip-ring engaging the pipe whilst longitudinal forcing causes it to be forced into the body simultaneously abutting against and compressing the seal whilst dragging the pipe further into the body. The nut and the body may further have tapered surfaces that are brought together as the grip-ring is forced into the body. The physical connection between the body and the nut provides reinforcing for the nut, a feature especially useful when dealing with soft plastics. Further features include a lip on the grip- ring that provides an additional support for the grip-ring when compressed as well as an abutment shoulder on the nut preventing the grip-ring form being pulled out of the body.
