Link-Seal Modular Seals

The best way to permanently seal any cylindrical object, of any size, passing through any type of concrete barrier(wall, floor or ceiling) is to use Link-Seal® modular seals. From ductile iron to pre-stressed concrete to metal or plastic pipe, conduit or cables - whatever your application - Link-Seal® modular seals will effect a hydrostatic seal capable of holding 20 psig (40 feet of static head) between the pipe and the penetration cylinder through which the pipe passes.
