Rod seals

Rod seals are primarily used in the hydraulic industry. Rod seals are found in hydraulic cylinders. Rod seals act as a pressure barrier and ensure the retention of the operating fluid inside the hydraulic cylinder. They thus have a crucial sealing function in hydraulics.

Rod seals also help regulate a thin film of lubricant on the rod's surface as it moves, preventing corrosion of the rod and promoting the lubrication of the wiper.
