109 Series: 109 Rod Seal - or Energizer
The 109 Series rod seal is a low-friction design, consisting of a PTFE-filled seal and an O-ring energizer.
109 Series
The 109 Series Rod Seal is ideal for high-pressure sealing applications, offering low-friction performance and high-speed capability. 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.

Material Ranges
The 106 Series rod seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100mm in diameter, MP50 and MN01 injection-molded TPU. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
