O Ring

An O ring is a loop of elastomer with a round cross section used as a mechanical seal or a gasket. An O ring is designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

The joint may be static or have relative motion between the parts and the O ring, rotating pump shafts and hydraulic cylinders, for example. Joints with motion often require lubrication of the O ring to reduce wear. The best form of lubrication is often accomplished by the fluid being sealed.

O rings are one of the most common seals and are used in a number of industries for different applications. O rings are inexpensive and simple to make, reliable and easy to mount. They have the ability to seal huge amounts of pressure.

Successful O ring design requires a rigid mechanical mounting that applies a predictable deformation to the O ring. This introduces a calculated mechanical stress as the O ring contracting surfaces. As long as the pressure of the fluid contained does not exceed the contact stress of the O ring, leaking will not occur.

The seal on the O ring is designed to have contact between the O ring and sealing faces, allowing a high local stress and the ability to contain large amounts of pressure, without exceeding the yield stress of the O ring. The flexibility of the O ring accommodates imperfections in the mounting parts.
