Overview

• The PI Piston Seal provides superb sealing performance and very long service life.
• Single acting design can be used separately for single acting cylinders or in back-to-back tandems for double acting cylinders.
• Asymmetrical design assures the highest performance by preventing tipping and twisting in the housing.
• Knife-cut lips on both the dynamic and static sides assures maximum sealing force to provide maximum motion control while preventing drift.
• The PI Piston Seal is made from DISOGRIN 9250, world renowned for its resistance to wear and tear and for its very low compression set.
• The result is superior performance and longer operating life.
• The PI is resistant to pressure spikes and diesel effect. Capable of withstanding pressures up to 6,000 psi and 300°F (intermittent), the PI Piston Seal is excellent choice 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.
