The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to propane and butane, many alcohols, and water. Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.
