Product Overview An O-ring is a ring-shaped sealing component with a circular cross-section. Its size is primarily defined by the inner diameter (ID) and the cross-section diameter (CS). The outer diameter can be calculated using the formula: OD = ID + 2 * CS . O-rings are used to prevent the leakage of liquids and gases, helping to maintain reliable sealing performance in piping systems, hydraulic and pneumatic equipment, automotive components, and industrial machinery.
