As a material, Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, strong abrasion and tear resistance. It resists many alcohols, greases and lubricants, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where automotive brake fluid or polar solvents are present.
Common environments for this compound include hydraulic and pneumatic systems, construction equipment, and agricultural equipment.
Order part number H2.4X17.8, sold individually. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
