A guide to Perlast perfluoroelastomers and other high performance elastomers.
An O-ring, or toroidal seal, is the most common type of seal used in the world today.
Used to form a physical barrier to prevent the mixing of gases or liquid fluids, the simple toroidal shape of an O-ring has proven to offer high sealing efficiency across a wide range of applications.
