The Schluter®-KERDI-SEAL system includes a Mixing Valve Seal, it is designed to work in addition to the Pipe Seal (sold separately). These are prefabricated sections of KERDI with over-molded rubber gaskets. These components are essential for effectively sealing pipe protrusions through the KERDI waterproofing membrane, particularly in areas such as shower-heads and tub spouts. They also provide critical protection for moisture-sensitive backing panels at the mixing valve, ensuring the long-term durability and performance of the system. Trust Schluter to provide the comprehensive sealing solutions you need for your next project.
