What is O-rings?
O-rings are annular sealing devices commonly used in various industries to prevent the passage of liquids, gases, or other contaminants between two surfaces. They are made from a flexible material, usually silicone or a synthetic elastomer such as nitrile, rubber, or Viton. The main function of the O-ring is to compress itself to achieve a tight sealing when the two surfaces are assembled.
Because of their simplicity, low cost, and high efficiency, O-rings are widely used in various applications such as automotive, aerospace, hydraulic systems, and chemical processing. They come in a variety of sizes, materials, and hardness levels to suit different environmental conditions and pressure requirements. Proper selection and installation of O-rings are essential to ensure the desired sealing performance and extend the service life of the component.
Types of Material Used to Construct O-rings
O-rings are used in applications that require resistance to pressure, temperature, and chemical exposure. To cater to these diverse requirements, O-rings are made from various materials. Here are some common materials used to construct O-rings:
