The 188 Series rod seal is a heavy duty, low-friction design, consisting of a PTFE filled seal, a profiled energizer and an integrated backup ring. 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.

Compatible with a wide range of media
Available in diameters up to 2100 mm
The 188 Series Heavy-Duty Rod Seal with Integrated Backup Ring is ideal for high-pressure sealing applications, offering low-friction performance and short-stroke capability.
Typical Applications
The 188 Series is a custom blended PTFE filled compound that provides 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 backup ring can be made from Polyamide, Delrin or POM. The temperature range of the seal can be increased by selecting a FPM energizer in place of the standard NBR energizer.
