Overview

• The Symmetrical U-cup provides excellent sealing performance and very long operating life in both rod and piston applications.
• Knife-cut lips on both the dynamic and static sides assures maximum sealing force to prevent leakage.
• The Symmetrical U-cup is made from DISOGRIN 9250, world renowned for its resistance to wear and tear and for its very low compression set. Its extrusion resistance is second to none.
• The result is superior sealing performance and longer operating life.
• The Symmetrical U-cup is resistant to pressure spikes and diesel effect. Capable of withstanding pressures up to 4,000 psi and 300°F (intermittent), the Symmetrical U-cup is a great for those tough applications with high pressures or temperatures where other seals fail.
• No adhesion effect on sliding surface, even after a long standstill.
• Superior performance over a wide range of temperatures and hydraulic fluids.
