Encapsulated O Rings are a specialized type of sealing ring designed to provide exceptional resistance to chemicals, high temperatures, and extreme pressures. They are constructed with a core material, usually made of silicone or Viton, that is encapsulated with a thin layer of PTFE. This unique design offers the benefits of both materials, providing the resilience and elasticity of rubber with the chemical resistance and low friction properties of PTFE. Encapsulated O Rings are widely used in demanding applications such as chemical processing, pharmaceutical, and food industries, where reliable and long-lasting sealing performance is crucial.
