LINK-SEAL® modular seals, by GPT, are considered to be the premier method for permanently sealing pipes of any size passing through walls, floors and ceilings. In fact, any cylindrical object may be quickly, easily, and permanently sealed against the entry of water, soil, or backfill material.

For the system approach, metal or non-conductive Century-Line™ sleeves with water stops may be ordered with LINK-SEAL® modular seals to ensure correct positioning and a water tight seal of the installation within poured concrete walls.


With a global focus on safety, reliability and sustainability, GPT produces innovative solutions that enhance the integrity of pipeline systems today to meet the demands of tomorrow.
