A Hydraulic Jack PU Seal is a sealing component made from Polyurethane (PU), designed for use in hydraulic jacks or lifting systems. These seals are critical in ensuring that the hydraulic fluid remains sealed within the system, preventing leaks and maintaining the pressure required for lifting operations. PU seals are specifically chosen for their excellent wear resistance, durability, and high performance under pressure, which are essential for the safe and effective operation of hydraulic jacks.
