    Proco Products, Inc. is excited to announce the release of a useful tool to help aid in the proper selection and installation of pipe penetration seals (Pen-Seals) into a piping system. The Proco Pen-Seal Calculator is designed to assist in selecting the correct number of links and the correct size of link for pipe penetrations passing through walls or floors. To achieve a 100% water or gas tight seal, enter in the pipe O.D and the penetration I.D. to provide the required size/link combination.

    What exactly is a Pen-Seal? Pipe Penetration seals have been designed to assist in achieving an efficient, low-cost mechanical seal when piping passes through walls, floors, tanks, pipeline castings or vaults. The unique design of the Pen-Seal helps to provide a gas or watertight seal, filling any space around a pipe. The standard elastomer for the Pen-Seal is EPDM and can be used in various applications in Power-Gen, HVAC, Water & WasteWater, Mining, etc.

    Within in the new Pen-Seal Calculator, you can also access the company website, view the Pen-Seal brochure PDF, contact a Proco representative and view an installation video. This video gives you a step-by-step visual of how to properly install a Pen-Seal from Proco. We encourage you to download this exciting & useful tool today on the appropriate platform for your device.
