Petersen® Multi-Flex™ Annular Seals

Petersen can manufacture Annular Seals for almost any size, pressure, chemical, and temperature requirements. Annular seals can be made with a continuous seal to slip over the end of a pipe or open-ended to form around a pipe already in place. The Petersen® Multi-Flex™ Annular Seals are very flexible, easy to install, and have many inflation connection options. These seals are ideal for bypassing a pipeline during repairs or any other temporary small to large pipeline connection.
