The HSN90461 is an AS568-461 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 15.955 in (405.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 16.505 in (419.23 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

HNBR (Hydrogenated Nitrile) offers improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. Expect good resistance to ozone and weathering, modern refrigerants, and heat and oxidation. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service.

You will find this material specified across automotive air conditioning, heavy-duty powertrain, and engine timing systems.
