Piston Square Ring

These seals have high sealing efficiency and shape stability. PolyMod® and UltraMod™ low friction Square Rings are preferred for dynamic applications. 

Available in many aerospace formulations. UltraMod™ low friction Square Rings are only available in fluoroelastomer materials.

Operating Ranges:

  • Pressure: Up to 7,250 PSI (50 MPa) and higher, depending on gap sizes
  • Temperature range: Approximately -65°F to +392°F (-54°C to +200°C), depending on the elastomer choice
