Repair couplings for all pipe materials. Can also be used as a non-tensile pipe coupling. Depending on the opening, the couplings support a bending angle of 2° to 5° and axial movement of 5 mm. When installing, the locking screws must be tightened to the correct torque. The torque is specified on the coupling.

Field of application

Water distribution
Gas pipelines
Cooling water

Features
