It compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to greases and lubricants, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ozone and direct sunlight.
Typical settings include fluid power, agricultural equipment, and general industrial maintenance.
