Description

LINK-SEAL® is the original modular elastomer sealing system, engineered to create a permanent hydrostatic seal around pipes and other cylindrical objects passing through concrete walls, floors, and similar barriers. Its durable construction helps protect against water intrusion, corrosion, and contamination across a wide range of industrial applications.

LINK-SEAL® Model C features black EPDM sealing elements paired with zinc-plated carbon steel hardware and a reinforced nylon polymer pressure plate for dependable performance in damp environments. Built for everyday pipe penetration sealing, it guards reliably against moisture, groundwater, and organic chemicals in interior piping systems and direct-burial applications. Its combination of proven durability and economical carbon steel hardware makes it a practical choice for general-purpose wall, floor, and vault penetrations throughout commercial and industrial construction.
