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.
