568-380 GREEN HNBR (HSN) 70 ORINGS

The HS70380 is an AS568-380 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 11.475 in (291.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 11.895 in (302.13 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to ozone and weathering, heat and oxidation, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is widely chosen for long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It should not be specified for service in ketones or chlorinated hydrocarbons.

Maintenance and OEM teams specify it across engine timing systems, automotive air conditioning, and heavy-duty powertrain.

Reference part number HS70380 when ordering; the item is sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
