The Schluter Kerdi-Seal-PS pipe seal underlayment is designed to create a secure, waterproof connection around pipe penetrations in tiled showers and wet areas. Measuring 6-3/4 in. x 6-3/4 in. with a 3/4 in. rubber gasket, this pre-formed seal integrates seamlessly with Schluter Kerdi waterproofing membranes.
The flexible rubber gasket ensures a tight fit around pipes, while the polyethylene sheet provides a waterproof layer that bonds easily to thin-set mortar. By eliminating the need for makeshift sealing methods, the Kerdi-Seal-PS pipe seal saves installation time and guarantees leak-proof performance.
