Piston Seal – HD Energizer – AE Ring



Low friction

Double acting applications

High-temperature resistance

Low wear

Compatible with a wide range of media

Available in diameters up to 2100 mm


The 288 Series heavy-duty piston seal is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.

Typical Applications

  • Forging Presses
  • Extrusion presses
  • Stamping presses
  • Rolling Mills
  • Injection Molding Machines
  • Hydraulic Presses

The 288 Series is made from custom blended PTFE filled compounds that provide ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFE filled with Bronze filler, or PTFE filled with Glass-Moly. The backup rings can be made from Polyamide, Delrin and POM. The temperature range of the seal can be increased by selecting a FPM energizer in place of the standard NBR energizer.
