Ordered as HS70147, this is an AS568-147 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.675 in (67.95 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.881 in (73.18 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, strong resistance to rapid gas decompression. The material holds up against heat and oxidation, modern refrigerants, and petroleum oils and fuels. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or chlorinated hydrocarbons.
Maintenance and OEM teams specify it across automotive air conditioning, heavy-duty powertrain, and engine timing systems.
Order part number HS70147, sold individually. Review your operating media and conditions against this specification before installation.
