This material stands up to petroleum-based oils, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or ozone and direct sunlight are present.
Typical settings include agricultural equipment, automotive, and fluid power.
Order part number HQ4453, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
