The 119 Series Spring energized rod seal is one of System Seals’ most popular designs used in standard to moderate-duty applications. The spring energized design ensures the seal lip forces are optimized for every cross section and diameter over a long period of time. Manufactured in a variety of materials and sizes to fit most applications requiring low friction, high temperature, and improved fluid compatibility.
Wide temperature range
Highly extrusion resistant with the use of a backup ring
Excellent fluid compatibility including water-based fluids and aggressive fluids
Exceptional low friction performance
Available in all standard sizes
Optional spring alloys available for improved performance and compatibility
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.
