An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against water, petroleum-based oils, and greases and lubricants. Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or strong acids will shorten service life.
