Basic Concepts of O-Ring Seals

An O-Ring Seal is a toroidal (ring-shaped) elastomer with a circular cross-section used to create seals in various mechanical systems. Its general function is to provide a barrier that prevents the leakage of fluids and gases. O-Ring Seals operate by being compressed between two surfaces, creating a seal that is both pressure-tight and resistant to extrusion. They are widely used in applications where a reliable seal is required under varying conditions of pressure, temperature, and chemical exposure ¹.
