Heavy-Duty Rod Seal

Series 190: Heavy-Duty Rod Seal

The 190 Series rod seal is a heavy-duty, low-friction design, consisting of a PTFE-filled seal and a profiled energizer. It is designed for large diameter and challenging applications, where high pressure and large extrusion gaps exist. The seal is ideal for short-stroke, dithering applications.



Low friction

Short-stroke applications

High-temperature resistance

Low wear

Extrusion resistant

Compatible with a wide range of media

Available in diameters up to 2100 mm


The 190 Series heavy-duty rod seal is ideal for high-pressure sealing applications, offering low-friction performance and short-stroke capability.

Typical Applications

  • Rolling Mills
  • Injection Molding Machines
  • Hydraulic Presses
  • Forging Presses


The 190 Series is made from custom blended PTFE-filled compounds that 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 energizer in place of the standard NBR energizer.
