Kabu-Seal is a pressure sealing ring made of a solid rubber core (EPDM) with a soft thermoset elastomer (PUR) jacket in yellow and compressive flanges made of stainless steel.
This water pressure-tight wall lead through is used for Kabuflex® conduits for building and wall lead throughs.

An advantage is its soft surface which offers sealing of the cable duct and core drill hole up to 1.5 bar water pressure.

Thanks to its very good adhesive properties, the Kabu Seal pressure sealing ring seals reliably (against pressurised water and gas) in the annular space even with very low tightening torque of the screw connection. Can be installed successfully without using special tools (torque spanner) at sight (yellow bead) at the compressive flange edges.
