Polyurethane seals are a widely used sealing component in hydraulic and pneumatic systems. PU seals are commonly applied as wipers, backup rings, or primary seals in hydraulic cylinders, valves, pumps, and other mechanical equipment to prevent leakage of oil, gas, or fluids while withstanding high pressure and harsh operating environments.
