O-Rings

An O-ring is a round mechanical gasket designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. O-rings may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.

O-rings are one of the most common types of seals because they are inexpensive, easy to make, reliable, and have simple mounting requirements. Furthermore, O-rings are one of the simplest, yet most engineered, precise, and useful seal designs ever developed. They are one of the most common and important elements of machine design.
