Link Seals District Cooling Products

Link Seals form a mechanical seal between pipes going through walls, floors, vaults, tanks and pipeline casings. Besides being designed to form a hydrostatic seal of up to 40 PSIG and up to 92.28 ft. of head pressure, It help absorb vibrations, shocks, and sound waves.

Being non-conductive, electrically isolate the inner carrier pipe from the penetrated structure. With this being a desired property in many applications in preventing a shorting effect from stray currents, it is particularly useful in sealing the gap between electrical conduit and the outer conduit or between electrical conduit and the opening.

They are made from synthetic rubber with heavy-duty, UV and ozone resistant plastic pressure plates. It can be installed easily and quickly by one worker with no special tools required.
