HNBR (Hydrogenated Nitrile) is known for improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. The material holds up against petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where ketones or esters are present.

It sees regular use in automotive air conditioning, heavy-duty powertrain, and engine timing systems.

Order part number HS70361, sold individually. Nominal inside diameter is listed as 6 inch. Check the compound against your process media, pressure and temperature before committing to a design.
