This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Expect good resistance to water, propane and butane, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving polar solvents or ketones call for a different compound.
This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across general industrial maintenance, hydraulic and pneumatic systems, and fluid power.
Order part number H70MD472, sold individually. Nominal inside diameter is listed as 23 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
