O-rings are one of the most common and important parts in almost every moving machine or part. O-rings are available in a large number of standard sizes and material. We will attempt to help you identify the size, compound, and were to purchase the o-rings you needed for all your application.
An O-ring is a loop of elastomer with a round (o-shaped) cross-section used as a mechanical seal. They are 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 parts and o-ring (rotating pump shafts and hydraulic cylinders, for example). Joints with motion usually require lubrication of the o-ring to reduce wear. This is often accomplished with the fluid being sealed.
O-rings are one of the most popular seals used in machine design because they are inexpensive and easy to make, reliable, and have simple mounting requirements. They can seal many thousands of psi.
Successful o-ring joint design requires a rigid mechanical mounting that applies a predictable deformation to the o-ring. This introduces a calculated mechanical stress at the o-ring contacting surfaces. As long as the pressure of the fluid being contained doesn't exceed the contact stress of the o-ring, leaking cannot occur.
