The O-Ring is now without question the world’s most versatile seal due to its simple shape, its minimal space requirement and its availability in a vast selection of sizes and compounds. It is one of the most highly critical, precision mechanical components ever developed. Easy to install and able to withstand both high pressures and temperatures, it can be used in a range of applications, both static and dynamic. We offer a varied selection of sizes in materials such as Nitrile, Viton, EPDM, Silicone and Kalrez.
