Kabu-IN DD is a pressure sealing ring made of a soft thermoset elastomer (PUR) in yellow, from NW 110 additionally with a solid rubber core (EPDM) and stainless steel compressive flanges.
This gas and water pressure-tight internal seal is used for Kabuflex® conduits for house and building penetrations.
The advantage is its soft surface which creates a reliable seal against gas and water pressure.
Thanks to its very good adhesive properties, the Kabu-IN DD pressure sealing ring fits reliably (against pressing water and gas) in the conduit. It can be installed successfully via visual indication (yellow bead) at the compressive flange edges. When positioning, please make sure that the internal seal is in the area of the unfinished flooring or screed and/or the Kabu Seal outside seal to establish a reliable seal.
