UFlow Seals are made with tough nylon flanges and stainless steel screws that provide the necessary strength torque to compress the EPDM rubber gasket. The seal is activated by tightening the internal screws with the UFlow screwdriver. This compresses the thermoplastic seal, forcing it to expand and make contact with the wall of the old pipe This prevents vertical movement and stops water backup damage. This design feature is incorporated in all UFlow retrofit drain products.
