installation illustration 271

Benefits

Low friction

Double-acting applications

High-temperature resistance

Low wear

Compatible with a wide range of media

Extrusion resistant

Available in diameters up to 2100mm

Applications

The 271 Accumulator Piston Series is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.

Typical Applications include:

  • Rolling Mills
  • Injection Molding Machines
  • Hydraulic Presses
  • Agricultural Hydraulics
  • Mobile Hydraulics

System Seals™ custom blended PTFE-filled compounds provide ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFE with Bronze filler, or PTFE filled with Glass-Moly. The temperature range of the seal can be increased by selecting an FPM energizer in place of the standard NBR energizer.
