Basic Concepts of O-Ring Seals

An O-Ring Seal is a toroidal (ring-shaped) elastomer with a circular cross-section, used to create a seal between two or more parts. In mechanical systems, O-Ring Seals are employed to prevent the leakage of fluids and gases, ensuring that systems operate efficiently and safely. They function by being compressed between two surfaces, creating a barrier that blocks the passage of substances. The effectiveness of an O-Ring Seal depends on its material properties, the design of the sealing surfaces, and the environmental conditions it operates under ².
