Applications

The 119 series rod seal is ideal for most applications requiring low friction, high temperature, and improved fluid compatibility.

Typical applications include:

  • Hydraulic and Pneumatic Cylinders
  • Pressure Accumulators
  • Valve Stems
  • Nozzles
  • High Temperature
  • Aggressive Fluids

The 119 series rod seal features low friction PTFE energized with an internal spring. Standard materials are MT200 PTFE filled with Carbon/Graphite, available in standard sizes using a stainless steel spring. Also available with Elgiloy spring as an option for high heat or added chemical resistance. To suit a variety of applications, the series is also available in various filled PTFEs as well as Polyurethane and UHMW.
