Piston seals

Hydraulic piston seals are critical components used in hydraulic cylinders to prevent fluid leakage and maintain pressure. They are widely applied in industries such as construction (excavators, loaders), agriculture (tractors, harvesters), manufacturing (presses, injection molding machines), automotive (braking systems, suspensions), and aerospace (landing gear, actuators). These seals ensure efficient power transmission, durability, and contamination control in high-pressure environments. Common materials include polyurethane, rubber, and PTFE, chosen based on operating conditions like temperature, pressure, and fluid compatibility. Proper sealing enhances equipment performance, reduces downtime, and extends service life.
