568-330 GREEN HNBR (HSN) 70 ORINGS

Part number HS70330 is an AS568-330 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) delivers excellent abrasion and tear strength, long service life in refrigerant and oilfield duty. It resists modern refrigerants, petroleum oils and fuels, and ozone and weathering. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to chlorinated hydrocarbons or esters will shorten service life.

You will find this material specified across engine timing systems, oilfield and downhole equipment, and automotive air conditioning.

Reference part number HS70330 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
