This material stands up to propane and butane, many alcohols, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or polar solvents call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across construction equipment, fluid power, and agricultural equipment.
