Link-Seal® Modular Seals, by GPT
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.
Standard size Link-Seal® modular seals can be used with Century-Line® Model CS sleeves, Model WS (Steel) sleeves, or core drilled holes. Link-Seal® modular 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.

Link-Seal® Sleeve Options
Century-Line® Model CS Sleeves
ideal for poured wall construction. Made of HDPE thermoplastic, they are lightweight 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.
Link-Seal® Modular Seals
Commonly installed in cored wall openings or pre-cast openings such as those formed by use of Cell-Cast® Disks for pipe penetration hole forms. Please see our Cell-Cast Disk pages.
Model WS Steel Sleeves
Made from heavy-wall 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. Mo del 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.
Installation - Link-Seal® Modular Seals
1. Center the pipe, cable or conduit in wall opening or casing. Make sure the pipe will be adequately supported on both ends. Link-Seal® modular seals are not intended to sup-port the weight of the pipe.
2. Loosen rear pressure plate with nut just enough so links move freely. Connect both ends of belt around the pipe.
3. Check to be sure all bolt heads are facing the installer. Extra slack or sag is normal. Do not remove links if extra slack exists. Note: On smaller diameter pipe, links may need to be stretched.
4. Slide belt assembly into annular space. For larger size belts, start inserting Link-Seal modular seal assembly at the 6 O'Clock position and work both sides up toward the 12 O'Clock position in the annular space.
5. Using a hand socket or off-set wrench ONLY, start at 12 o'clock and tighten bolts until rubber begins to "bulge" Do not tighten any bolt more than 4 turns at a time. Continue in a clockwise manner until links have been uniformly compressed. (Approx. 2 or 3 rotations)
6. Make 2 or 3 more passes at 4 turns per bolt max, tightening all bolts clockwise until all sealing elements bulge around all pressure plates. On type 316 stainless steel bolts, hand tighten ONLY without power tool.
7. If the seal doesn't appear to be correct using the instructions provided, call CCP at 310-532-9314
Installation Notes: The Link-Seal® modular seal bolt heads are usually recessed below the wall opening or the edge of casing pipe; therefore a socket or offset wrench must be used.
Hand Tools: Use 5/16" hex or #6 screwdriver for LS-200. 1/2" hex requires 3/8" drive socket wrench. 9/16" and 3/4" hex requires 1/2" drive socket wrench. Tools not provided.
