Compact seal insert particularly suitable for:
- Thin-walled plastic pipes
- Plastic-covered pipes (district heating)
Our Pipe-Seal Hybrid (PE) is a seal insert is a two-component construction with an external round frame of medium-hard solid rubber and an internal seal insert of soft thermoset elastomer.
The medium-hard solid rubber core absorbs the compressive or pressing force and transfers and distributes the medium. The soft inner ring acts as a seal towards the carrier pipe.
The extra soft seal insert adapts itself perfectly to the surface of the carrier pipe. High compressive or pressing forces are not necessary. A cold flow, which leads to cross-sectional tapering especially with polyethylene-(PE)-pipes, is nearly ruled out.
Even with a low torque of the screw connection, the seal insert sits firmly in the annular space (against pressing water and gas) as it adheres very well to the surface of the carrier pipe. The insert can be installed without any special tools (torque wrench) by visually inspecting the edges of the pressure flange (red bulge).
