About this app
The PROCO Pen-Seal calculator is designed to assist you in selecting the correct number of links and the correct size of link for pipe penetrations passing through walls and/or floors. To achieve a 100% water-tight seal, enter in your Pipe O.D. dimension and your Penetration I.D. to provide you with the required combination. The Pen-Seal’s standard elastomer material is EPDM, which is suitable for temperatures ranging from -40F to 250F. All sizes have been tested to withstand a hydrostatic seal up to 20 psig or 40 feet of head pressure. Used for various applications in Power-Gen, HVAC, Water & Wastewater, Mining, etc.
