288 Series: Piston Seal – HD Energizer – AE Ring
The 288 Series Heavy-Duty Piston Seal is a low-friction design, consisting of a PTFE fill seal, a profiled energizer and two integrated backup rings.
288 Series
The 288 Series Heavy-Duty Piston Seal with Integrated Backup Ring is a low-friction design, consisting of a PTFE filled seal, a profiled energizer and two integrated backup rings. It is designed for large-diameter, double-acting cylinders in challenging applications, where high pressure and large extrusion gaps exist.
Installation Drawing
Material Ranges
The 288 Series is made from custom blended PTFE filled compounds that provide ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFE filled with Bronze filler, or PTFE filled with Glass-Moly. The backup rings can be made from Polyamide, Delrin and POM. The temperature range of the seal can be increased by selecting a FPM energizer in place of the standard NBR energizer.
