Link-Seal® mechanical 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, easy and permanently sealed, as they pass through barriers, by the patented Link-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).

Electical 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 is easly configured to archieve 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 application.

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

This brochure focuses on standard size Link-Seal's for use with CenturyLine® Model CS, Model WS (Steel) or core drilled holes. Link-Seals are also available for a wide variety of special applications, temperature extremes, exotic chemical combinations and for "out of round" or non-centered applications. Please contact factory for your special application.

Saves time and money...
Link-Seal install in up to 75% less time compared to leadoakum joints, hand fitted flashings, mastics or casing boots.

Positive hydrostatic seal...
Link-Seal is rated at 20 psig (40 feet of head), which exceeds the performance requirements of most applications.

Long seal life...
Link-Seal is 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 organic resin coating or corrosion resistant 316 stainless steel.

Certification/Approvals...
Factory Mutual Fire Approvals. Det Norske Veritas Marine Deck/Bulkhead Penetration Certification. ANI (American Nuclear Insurers). Also a wide variety of approvals from various Federal agencies, associations, code groups, laboratories and organizations.

ISO Quality Assurance...
Link-Seal is manufactured in an ISO 9002 certified facility.

Configure a Link-Seal to match your application...
Color coded EPDM, Nitrile, & Silicone Elastomers may be used with various hardware options to match performance characteristics with service conditions.

CenturyLine® Model CS sleeves are ideal for poured wall construction. Made of HDPE thermoplastic, they are lightweaght and easy to handle. Molded-in waterstop and reinforcing ribs serve to anchor the sleeve in the wall and resist pour forces. Nailer end caps are provided to make placement in forms simple and accurate. Sleeves are available in 16 diameters, up to 25", and any length. In the event of a field change they can be shortened with ordinary hand tools.

Model WS Steel sleeves are made from heavywall welded or seamless pipe. A full circle waterstop plate acts as positive water seal and anchor to prevent thrust movement. The collar is continuously welded on both sides. Model WS is available in a wide range of diameters and any length. Sleeves are protected by a coating of red primer. Hot dip galvanizing is available on request.

Link-Seals are also commonly installed in cored wall openings or pre-cast opening such as those formed by use of the Thunderline Cell-Cast® pipe penetration hole form. See Cell-Cast literature or contact PSI for more information.
