Link-Seal modular seals 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, as they pass through barriers, by the patented Link-Seal modular seal design.

Ductile iron, concrete, metal as well as plastic pipes may be hydrostatically sealed within walls to hold up to 20 psig (40 feet of head). Electrical or telecommunications cable may be sealed within conduit as they enter vaults or manholes. The annular space between carrier pipes passing through casings may be sealed against the entry of water, soil or backfill material.

With a wide variety of hardware/ elastomer combinations, Link-Seal modular seals are easily configured to achieve the best possible match for service conditions encountered. High temperature seals, fire seals (Factory Mutual Approved) and oil resistant seals may be ordered to meet special or unique service applications.

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.


  • Saves time and money. Link-Seal modular seals install in up to 75 percent less time compared to lead-oakum joints, hand fitted flashings, mastics or casing boots.
  • Positive hydrostatic seal. Link-Seal modular seals are rated at 20 psig (40 feet of head), which exceeds the performance requirements of most applications.
  • Long seal life. Link-Seal modular seals are designed for use as a permanent seal. Seal elements are specially compounded to resist aging and attack from ozone, sunlight, water and a wide range of chemicals.
  • Maximum protection against corrosion. Standard fasteners with a two-part zinc dichromate and proprietary corrosion inhibiting coating. Corrosion resistant 316 stainless steel available for maximum corrosion protection.
  • ISO Quality Assurance. Link-Seal modular seals are manufactured in an ISO 9001-2000 certified facility.
  • Configure a Link-Seal modular seal to match your application. Colour coded EPDM, Nitrile and Silicone elastomers may be used with various hardware options to match performance characteristics with service conditions.
