Pipe Penetration Seals
PROCO’s PEN-SEAL Pipe Penetration Seals have been designed to assist in
achieving an efficient, low-cost mechanical seal between any Electrical Conduit,
Concrete, Cast Iron, Steel, Copper, or PVC/CPVC pipes passing through Walls,
Floors, Tanks, Pipeline Casings, and Vaults. The PEN-SEAL, while being used to
seal the gap in electrical conduit lines, will also act as an insulator.
The PEN-SEAL has been designed to provide a gas and watertight seal. 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.
PEN-SEAL’s standard elastomer material is EPDM, which is suitable for tempera-
tures 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 insula-
tion where cathodic protection is required. Silicone material is also available
for higher temperature applications up to 400° F.
Where the PEN-SEAL may come in contact with Hydrocarbons, Oil, Gas, Jet
Fuel, and miscellaneous solvents, a Nitrile material is available with tempera-
tures ranging from -40° F to 210° F.
The PEN-SEAL utilizes glass-reinforced plastic for the pressure plates and all
hardware is manufactured from Steel Zinc Dichromate. For corrosion resistance,
Stainless Steel hardware is available upon request.
Various applications for the PROCO PEN-SEAL:
• Wall Sleeves • Precast Concrete • Valve Pits
• Floor Sleeves • Mining • Offshore Oil Platforms
• Interior Piping • Marine • Telecommunications
• Noise Dampener • Water & Wastewater • Dual Containment Seal
• Electrical Contractors • HVAC • Underground Steel Tanks
• Pulp & Paper • Power Generation • Coal Preparation Plants
