Applications
The 288 Series heavy-duty piston seal is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.
Typical Applications
- Forging Presses
- Extrusion presses
- Stamping presses
- Rolling Mills
- Injection Molding Machines
- Hydraulic Presses
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.
