System Seals’ custom blended PTFE 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 energizer in place of the standard NBR energizer.
