Seal rings are circular sealing components utilized throughout vehicle systems to prevent leakage of fluids or gases. Commonly found in engine, transmission, and hydraulic applications, they create a static or dynamic barrier between mating components. These rings are manufactured from materials like nitrile, silicone, or Viton, selected for chemical and temperature resistance specific to the application. Cross-sections vary from O-ring style to more complex lip designs, optimized for pressure and sealing requirements. Precise dimensions and material hardness are critical for maintaining effective sealing performance and preventing component failure.
