Pipe-Seal Senso®
Utility model, patent applied for

Compact seal insert particularly suitable for:

  • Thin-walled plastic pipes
  • Plastic-covered pipes (district heating)
  • Corrugated/flexible pipes


Our Pipe-Seal seal insert is a two-component construction with the carrier/core component made of medium-hard solid rubber and a covering element made of soft thermoset elastomer.

The medium-hard solid rubber core absorbs the compressive or pressing force and transfers and distributes the medium. The soft cover acts as a seal toward the carrier pipe, the core-drilled hole or the wall sleeve and toward the sides of the pressure flange (including the screw threads).

The extra soft cover element adapts itself even to extreme carrier pipe surfaces without difficulty.

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).

  • Pressure flange and connecting elements made of stainless steel
  • Carrier/core components made of solid rubber
  • Cover made of thermoset elastomer with excellent chemical, mechanical and thermal properties
