This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. This item is further identified as 40MMIDX2MMCS.

Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Expect good resistance to greases and lubricants, petroleum-based oils, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where automotive brake fluid or ketones are present.

Typical settings include hydraulic and pneumatic systems, agricultural equipment, and fluid power.
