O-Rings

O-Rings

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.

Did you know?

1933 – From his basement, Niels Christensen used trial and error to discover that a ring-shaped piece of rubber in a groove, made a reliable seal of a piston sliding in a cylinder. He applied for a patent and it was granted approximately two years later.
