Introduction to O-Rings
O - Rings are one of the most common types of seals used in various industries. They are doughnut - shaped mechanical gaskets that are designed to prevent the leakage of fluids or gases in a mechanical system. Typically made from elastomers such as rubber, silicone, or fluorocarbon, O - Rings are known for their simplicity, reliability, and cost - effectiveness. They can be found in a wide range of applications, including automotive engines, hydraulic systems, plumbing, aerospace equipment, and household appliances. Their ability to create a tight seal under different pressures, temperatures, and chemical environments makes them an essential component in modern engineering.
