Installation Instructions PSI Link-Seal Modular Seals


Engineered seals for sealing pipes through walls, floors & casings.
Also see PSI Link-Seal Installation Video.

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 support 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.

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.

Always Wear Safety Equipment when Installing or Using Link-Seal® modular seals!
