208 Series: Piston Seal – OR Energizer
The 208 Series standard-duty piston seal is a low-friction design, consisting of a PTFE-filled seal and an O-ring energizer.
208 Series
The 208 Series standard-duty piston seal is a low-friction design, consisting of a PTFE-filled seal and an O-ring energizer. It is designed for double-acting cylinders in challenging applications, where low friction and high wear resistance are needed.

Material Ranges
System Seals™ custom blended 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 an FPM energizer in place of the standard NBR energizer.
