*HSN (HNBR) 80 568-266

Ordered as HSN80266, this is an AS568-266 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 7.984 in (202.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.262 in (209.85 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. It resists ozone and weathering, sour gas and amine inhibitors, and modern refrigerants. 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, commercial refrigeration, and engine timing systems.

HSN80266 ships individually. Nominal inside diameter is listed as 8 inch. Review your operating media and conditions against this specification before installation.
