- Plastic Pipe Internal Restraint Joints
HydroGrip Series
Formerly known as RieberLok, HydroGrip gaskets are internal restraints designed for PVC applications. Engineered with metal teeth embedded in the rubber to lock the gasket in place, HydroGrip converts a conventional joint into an internal restraint joint, eliminating the need for bolt-on harness restraints, clamps, thrust blocks, or other external or internal restraint technology on your PVC piping systems. Combined with the ease of installation, HydroGrip provides significant savings in installation time and material cost.
