The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to petroleum-based oils, water, and greases and lubricants. Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound.

Common environments for this compound include hydraulic and pneumatic systems, automotive, and general industrial maintenance.
