In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Expect good resistance to greases and lubricants, many alcohols, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or ozone and direct sunlight are present.

Maintenance and OEM teams specify it across fluid power, hydraulic and pneumatic systems, and agricultural equipment.
