This pipe-penetration seal can handle 40 ft of head pressure
The Pen-Seal (photo) is a pipe-penetration seal designed to assist in achieving a low-cost gas- and water-tight mechanical seal in situations where a pipe passes through walls, floors, tanks and more. All sizes of the Pen-Seal have been tested to withstand a hydrostatic seal up to 20 psig or 40 ft of head pressure, in addition to withstanding temperatures up to 250°F. The Pen-Seal’s standard elastomer material is ethylene propylene diene monomer (EPDM), but a nitrile material is available if the seal is used in applications where it may come in contact with hydrocarbons, oil, gas, jet fuel or miscellaneous solvents and where temperatures range from –40 to 210°F. Silicone material is also available for higher-temperature applications up to 400°F. The Pen-Seal utilizes glass-reinforced plastic, and all hardware is manufactured from steel zinc dichromate. For corrosion resistance, 316 stainless-steel hardware is available. This seal can be used with pipes of various materials, including electrical conduit, concrete, cast iron, steel, copper or polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC). While being used to seal the gap in electrical conduit lines, the Pen-Seal will also act as an insulator. Applications for the Pen-Seal include wall sleeves, floor sleeves, interior piping, noise dampening, mining, water and wastewater, valve pits, dual-containment seal, underground steel tanks, pulp-and-paper plants and power generation — Proco Products Inc., Stockton, Calif.
