Their airtightness directly affects the operating efficiency and life of the equipment. Oil seals are available in various sizes, ranging from micro to large, and are widely used in key parts such as engines, gearboxes, and steering systems to prevent leakage of lubricating oil or working media. Therefore, it is crucial to ensure that the airtightness testing of oil seals before leaving the factory meets high standards.
