The 282 Series heavy-duty piston seal is a low-friction design, consisting of a PTFE filled seal and a profiled energizer. It is designed for large-diameter, single-acting cylinders in challenging applications, where high pressure and large extrusion gaps exist.
Single acting applications
Compatible with a wide range of media
Available in diameters up to 2100 mm
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.
