Basic Concepts of O-rings

O-rings are circular elastomer seals that create a barrier between two surfaces to prevent the leakage of fluids and gases. They are widely used in mechanical systems due to their simplicity and effectiveness. O-rings are typically made from materials such as nitrile rubber, silicone, or fluorocarbon, chosen for their specific properties like resistance to chemicals, temperature, and pressure. They function by deforming slightly when compressed between two surfaces, creating a tight seal ¹.
