The main role of the oil seal is to seal the gap between the moving parts, prevent lubricant leakage, and remove contaminants from the mechanical system of the engine. In the automobile transfer box, the oil seal ensures that the lubricating oil does not leak, thus maintaining the normal operation and lubrication effect of the transfer box.
Automotive transfer box oil seal materials usually include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane and polytetrafluoroethylene. These materials have good sealing performance and durability, and can adapt to the working environment and conditions of the automobile transfer box
