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 components. Its general function in mechanical systems is to prevent the leakage of fluids or gases by deforming to fill the space between mating surfaces. O-Rings are commonly made from materials such as nitrile rubber, fluorocarbon, or silicone, chosen for their specific properties like chemical resistance, temperature tolerance, and durability. The seal is achieved through the O-Ring’s ability to deform under compression, creating a tight fit that blocks the passage of substances ².
