. The seal is carefully designed to provide a tight fit between the moving parts of the cylinder, such as the piston and the cylinder walls, to prevent any fluid from leaking out. Without a proper oil seal, hydraulic fluid could leak out of the cylinder, leading to a loss of pressure and potentially damaging the entire hydraulic system.hydraulic cylinder oil seal
