Backup Rings - Polyurethane

Overview

  • Provides exceptional extrusion resistance to a paired oring or seal to increase pressure handling capabilities.
  • High abrasion resistance makes it suitable in contaminated fluids.
  • Can be used as a backup to a hydraulic seal or an oring.
  • 95A Polyurethane.
  • Suitable for static and dynamic applications.
  • Suitable for high pressure and heavy duty applications where additional resistance to extrusion is required.
  • Hydraulic fluids, petroleum fuels and oils
  •
