Frequently Asked Questions

What pipe types and sizes is the Reverse Repair Clamp for Plastic Pipe compatible with?
The Reverse Repair Clamp for Plastic Pipe fits DN56.5 to DN177.5 pipelines and is engineered for PE (HDPE), PVC, and PPR. It seals longitudinal cracks, pinholes, circumferential fractures, and joint leaks without cutting out the damaged pipe section.
What is the working pressure rating?
Rated for 1.0 MPa. Standard clamp bodies are tested to at least PN16 (1.6 MPa); higher-pressure variants are available on request for gas-distribution and industrial service.
Can this clamp be installed on a live, pressurized pipeline?
Yes. The Reverse Repair Clamp for Plastic Pipe is designed for installation on live pipelines under pressure, which means municipal water, gas, or process flow does not have to be interrupted. Our technical team provides pre-install checklists to ensure safe deployment.
What materials are used in the body and sealing gasket?
