Dirt Wiper – Double Acting – OR Energizer



Protects the hydraulic cylinder internals


Works in short stroke applications

Works in high temperature environments


The 315 Series Heavy-Duty, Double-Acting Wiper prevents contamination ingress in harsh environments, while maintaining low friction.

Typical Applications

  • Forging presses
  • Extrusion presses
  • Stamping presses
  • Steel and aluminum mills
  • Injection molding machines
  • Cold and hot strip mills


The 315 Series Heavy-Duty, Double-Acting wiper consists of a custom-blended PTFE that provides ultra-low friction and high-speed performance with minimal wear. The standard compound is PTFE with Bronze filler. The temperature range of the wiper can be increased by selecting an FPM energizer in place of the standard NBR energizer.
