Introduction to O – rings
O – rings are circular seals with a cross – section in the shape of an “O”. They are widely used in various industries, such as automotive, aerospace, machinery, and plumbing. These seals are designed to prevent the leakage of fluids (liquids or gases) between two mating surfaces. O – rings are typically made from elastomeric materials like rubber, silicone, and fluorocarbon, which offer excellent elasticity, chemical resistance, and sealing performance. Their simple yet effective design makes them a crucial component in countless applications, ensuring the proper functioning and safety of many systems. O-rings
