Pipe Penetration Seal

Proco’s pipe penetration seals form a mechanical rubber seal between pipes going through walls, floors, vaults, tanks, and pipeline casings and makes a gas tight and watertight seal between a pipe and a wall hole. They can also be used to seal a gap between an inner pipe and an outer pipe sleeve or pipeline casing, a gap between an electrical conduit and the outer conduit, or between electrical conduit and the wall hole it passes through.

Proco’s pipe penetration seals have been designed to assist in achieving an efficient, low-cost mechanical seal between conduit, concrete, cast iron, steel, copper, or PVC / CPVC pipes passing through walls, floors, tanks, pipeline casings, cavities and vaults.

All sizes have been tested to withstand a hydrostatic seal up to 20 psig or 40 feet of head pressure in addition to withstanding temperatures up to 250° F. The pipe seal standard elastomer material is EPDM, which is suitable for temperatures ranging from -40° F to 250° F. EPDM is suitable for most applications in water—above ground and direct burial – and will provide the electrical insulation where cathodic protection is required. Silicone material is also available for higher temperature applications up to 400° F.
