Pipe systems are everywhere. They help move water or gas from one area to another, which is very important to cities and towns everywhere. However, it can be challenging to navigate the various structures that pipes come in contact with when installing new pipe systems. For that, there are link seals to save the day when problems arise! Link seals are very useful when it comes to sealing a pipe penetration. These mechanical systems help to seal the annular space around pipes that pass through concrete walls, floors, ceilings, and other barriers. Annular space is the space between pipe and core hole than can cause major issues for system installation. Link seals are the best method for sealing the annular space and are very easy to install. They are designed for special applications such as temperature extremes, chemical combinations, and slightly non-centered installations. Oil, gas, water, and air are no match for link seals! Link seals are able to fit any pipe, but it’s important that the correct size is established for best results.

LINK-SEAL 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 nonconductive sleeves with water stops may be ordered with link seal modular seals to ensure correct positioning and a watertight seal of the installation within poured concrete walls.
