Oil sel not only prevent the leakage of oil, water, chemicals, gases, and other substances (including lubricating oil used in machinery) from gaps and grooves to the outside, but also block the entry of dust and dirt from external sources.

Oil seals are indispensable components in sealing systems of machinery across various fields, including automobiles, aircraft, ships, rail vehicles, construction machinery, agricultural machinery, the petrochemical industry, and a wide range of household appliances.
