An O-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section. These seals prevent leakage and loss of liquids or gases in mechanical systems. O-rings are known for their simplicity, convenience, and minimal installation space requirements.

When proper groove design and material selection are implemented, and operating conditions remain within the rubber material's temperature range, O-rings provide long-term sealing effectiveness in both static and dynamic applications.

O-ring size is determined by inner diameter (ID) and wire diameter (CS). Outer diameter calculation: OD = ID + 2 × CS
