The 109 Series rod seal is a low-friction design, consisting of a PTFE-filled seal and an O-ring energizer. The sealing lip design is optimized to ensure maximum sealing performance at both low and high pressures. The lip design features a “pump-back” capability, which eliminates pressure trapping when used as a buffer seal in a Zero-Leak Technology configuration.
Low friction
High-speed applications
High-temperature resistance
Low wear
Extrusion resistant
Compatible with a wide range of media
Available in diameters up to 2100 mm
The 109 Series Rod Seal is ideal for high-pressure sealing applications, offering low-friction performance and high-speed capability.
Typical Applications
System Seals’ unique 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 a FPM O-ring in place of the standard NBR O-ring.
