Universal Rod or Piston U-Cups or U-Rings are popular due to the small gland space required. They are usually specified in low speed, low pressure environments for both pneumatic and hydraulic cylinders. The symmetrical design seal is obtained by means of the flared, flexible lips coming in contact with the rod or cylinder wall. Clearance is provided at the heel for minimum friction. Seal effectiveness is increased as internal pressure increases against the inner surface of the lips. Many different U-Cup configurations exist to properly seal that demanding application. The O-Ring Store LLC offers a wide range of U-Cup designs and produces them from a broad range of materials. Loaded U-Cups, Non loaded U-Cups, Hydraulic or Pneumatic U-Cups We make getting U-Cups easy!
