HYDRAULIC CYLINDER SEALS Hydraulic seals are used to prevent fluid leakage from hydraulic systems and to keep contaminants from entering the system. They are commonly used in a wide range of applications, including hydraulic cylinders, pumps, and valves. There are several types of hydraulic seals, including: Piston seals: These seals are used in hydraulic cylinders to prevent fluid leakage between the piston and the cylinder wall. Rod seals: These seals are used to prevent fluid leakage from the hydraulic cylinder around the rod. Wiper seals: These seals are used to prevent contaminants from entering the hydraulic system and damaging the rod and other components. Wear rings: These seals are used to prevent metal-to-metal contact between the piston and cylinder wall, reducing friction and extending the life of the hydraulic cylinder. Hydraulic seals are made from a variety of materials, including rubber, polyurethane, ptfe , fkm. The material selection depends on the specific application requirements, such as operating temperature, pressure, and fluid compatibility.
