That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with strong acids or ketones.
Common environments for this compound include fluid power, hydraulic and pneumatic systems, and agricultural equipment.
