Technimex’ pull-out resistance PE-/PVC-Grip pipe coupling PE and PVC pipes consists of a sleeve that is placed between two end-rings. Between end-rings and sleeve, grip rings, press rings and gaskets are positioned. The end-rings are pressed onto the sleeve when the bolts are tightened. The rubber gasket, pressed by the press ring and grip ring, then completely fills up the space between pipe and coupling.
By tightening the bolts, the press ring and the grip ring will press the gasket inside until the press ring makes contact with the sleeve. From then on the brass grip ring starts to reduce it’s diameter, and the sharp profile of the grip ring starts to cut into the PE pipe. After the bolts are tightened, until a metal-metal contact is reached, the coupling is ready for use.
Because of the strong compression and the high quality of the rubber gasket, the pressure on the ring that guarantees the leak tight sealing, will remain on the required quality level for many years.
