Basic Concepts of O-Ring Seals

An O-Ring Seal is a type of gasket with a circular cross-section, designed to create a seal between two or more parts. It operates by being compressed within a groove, which then deforms to fill the space between the mating surfaces, thereby preventing the passage of fluids or gases. O-Ring Seals are commonly made from materials such as nitrile rubber, fluorocarbon, or silicone, each offering different properties like resistance to chemicals, temperature, and compression set ².
