The 208 Series standard-duty piston seal is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.

System Sealsâ€™ custom blended PTFE-filledÂ compounds provide ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFEÂ with Bronze filler, or PTFEÂ 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.
