[0002] During the production and storage of lubricating oil, sealing cap fillers are used as an important sealing method in various containers to ensure that the lubricating oil is not contaminated by the outside world during storage and transportation, and to maintain its original quality and performance. Sealing cap fillers usually refer to fillers or structures embedded in the sealing cap to enhance the sealing effect, such as raised iron blocks.
