About This Product
Waterproof Seal for 3/4" Plumbing Penetrations
The HYDRO-BLOKĀ® Pipe Seal is a waterproof pipe collar designed to seal 3/4" plumbing penetrations in tile shower and tub waterproofing systems. It installs around inlet and outlet pipes to maintain a continuous waterproof barrier at wall and ceiling openings.
Compatible with Sheet and Liquid Waterproofing Systems
The pipe seal integrates with both sheet membrane and liquid waterproofing systems, helping maintain waterproof membrane coverage where plumbing pipes penetrate the assembly. It is suitable for new installations and waterproofing repairs requiring sealed pipe penetrations.
