Kabu-Seal is a pipe seal made of a solid rubber core with a soft yellow duroplast elastomer coating and stainless steel press flanges. The seal is used for gas- and water-tight building entry of Kabuflex® R plus pipes. The advantage is the soft surface, which creates a seal against the cable protection pipe and the core hole up to 1.5 bar water pressure. Due to the very good adhesive properties, the Kabu-Seal press ring sealing insert sits securely against pressing water and gas in the annular space, even with a very low tightening torque (2 Nm). Installation can be carried out successfully without special tools (torque wrench) using the visual contact indicator (yellow bead) on the press flange edges.
