Heavy-Duty, Double-Acting Wiper

Series 315: Heavy-Duty, Double-Acting Wiper

The 315 Series Heavy-Duty, Double-Acting wiper is one of the most popular heavy-duty wipers. It includes a reinforced PTFE-filled scraper ring and one energizing O-ring. The design incorporates a wiping lip to prevent contamination from entering the cylinder and an inner sealing lip to remove any oil film from the rod as it cycles. The O-ring energizes the two wiper lips. In most applications, a pressure relief port between the wiper and the rod seal is recommended.



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.
