Kabu-IN DD is a cable seal for one or more cables made of a soft yellow duroplast elastomer, from NW 90 a solid rubber core and stainless steel press flanges. This gas and water pressure-tight inner seal is used for Kabuflex® R plus pipes for building entries. The advantage is the soft surface, which creates a secure seal against gas and water pressure. Due to the very good adhesive properties, the Kabu-IN press ring sealing insert sits securely in the pipe, protecting it against pressing water and gas. Installation can be carried out successfully using the visual contact indicator (yellow bead) on the press flange edges. To ensure secure sealing, ensure that the inner seal is in the area of the unfinished floor or screed or the Kabu-Seal outer seal when positioning.
