Xyfluor® 860

Fluorinated Elastomer for Compression Molding


Xyfluor® 860, a highly fluorinated elastomer compound, offers excellent chemical compatibility over a wide range of temperatures from -76ºF to 450ºF (-60ºC to 232ºC). Recommended for applications requiring a combination of low-temperature properties and chemical resistance, Xyfluor’s capabilities surpass those of standard fluoro-elastomers, PTFE, and graphite. Additionally, Xyfluor reduces overall cost by extending equipment service life.


  • Dependable balance of physical properties at temperatures as low as -76ºF (-60ºC) and as high as 450ºF (232ºC)
  • Minimal sealing force required for low-sealing pressure applications
  • Excellent chemical resistance
  • Resistance to hydrocarbon fuels and lubricants
  • Good resistance to steam and water
  • Less likely to be damaged during installation a compared to PTFE and graphite
  • Better conformance to rougher surface finishes as compared to PTFE


Xyfluor 860 works well in demanding applications such as mechanical seals, gaskets and other custom components in a variety of metering pumps, valves and other high-performance equipment.
