Hydraulic cylinder seals are used on hydraulic cylinders to prevent hydraulic fluid from leaking and help keep dirt and other contaminants from entering the cylinders. Piston seals prevent fluid from leaving the chamber, which can reduce cylinder effectiveness. Dual rod and piston seals prevent fluid leakage on the rod and piston in low-pressure, low-speed applications. Rod wiper seals keep the rod clean of contaminants. V-ring seals protect bearings.
