O ring cross section.

The o ring may be used in static applications or in dynamic applications where there is relative motion between. Ideal for small components such as watches. It is a loop of elastomer with a round cross section designed to be seated in a groove and compressed during assembly between two or more parts creating a seal at the interface.
