Whether you need a industry standard size or made-to-measure seal, our O-rings are developed to be straightforward to use and make a tight seal whatever the application.

These donut-shaped rings come in all sizes and are developed to prevent the passage of water, steam, oil or air. They are used in anything from underwater cameras, to scuba gear to and a range of static and dynamic mechanical applications. They fit seamlessly into a groove and are then compressed to form a seal at the interface between the two parts.
