Pipe-Seal compact seal

Pipe-Seal compact seal insert

Our Pipe-Seal compact seals are designed for universal use in civil engineering in the sectors of power, gas and water distribution. 

They are suitable for the sealing of pipes and core-drilled holes with any diameter and can be installed inside a wall sleeve as well as directly inside a core-drilled hole. By tightening the screw nuts, the metal plates are pressed against the rubber seal ring, so that the elastomer ring expands steadily in all directions and reliably seals the pipeline. 

These seal inserts also provide guiding aid and offer acoustic uncoupling.

Special materials

Pipe-Seal Senso®

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).
