Create a weather-tight pipe or line seal for roof penetrations without the use of sealants or caulking. Won’t rust or corrode or conduct heat and cold like metal does. Our Exit Seals are injection molded from ABS resin that is both impact and UV resistant. The gaskets we use are made from long lasting EPDM rubber.

With close to 20,000 Sigrist Exit Seals® installed from coast to coast without a single failure or warranty return we confidently stand behind our limited lifetime warranty.

Sigrist Exit Seals® are manufactured in the United States using state of the art, computer aided injection molding systems. All parts are hand inspected three times before leaving our facilities; right out of the mold (hot), during assembly and at the time of filling each order fulfillment. We understand the critical nature of having the right parts on site during installation.
