This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. This material stands up to many alcohols, water, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or strong acids will shorten service life.
