The U-Cup Seal provides a dynamic seal between the Cylinder Head and its mating surfaces. It is made from an elastic material such as Rubber and helps effectively prevent the leakage of hydraulic fluid from the high-pressure side to the low-pressure side of the cylinder, ensuring proper functioning and performance.Attributes:• Exhibit high wear resistance• Offers excellent sealing performance by minimizing fluid leakageApplications:The U-Cup Seal is used in the hydraulic bucket cylinder helps to ensure a secure sealing connection reduce the friction created on the cylinder rod head and create a tight sealing for rod and cylinder in a hydraulic unit.
