Applications

The 263 series piston seal is ideal for sealing gaseous media or where zero cylinder drift is required.

Typical applications include:

  • Accumulators
  • Specialty high-pressure cylinders
  • Various advancing and secondary cylinders

The 263 series piston seal features custom blended PTFE-filled compounds that provide ultra-low friction and high-speed performance and minimal wear. The standard compounds are PTFE-filled with bronze filler or PTFE-fille with glass-moly. The 263 series features a robust elastomeric energizer with backup rings in a high strength thermoplastic. The temperature range of the seal can be increased by selecting an FPM energizer in place of the standard NBR energizer.
