Product Specification

-
This o-ring is supplied in AS568-312 green HNBR (Hydrogenated Nitrile) 70 Shore A measuring an inside diameter of 0.6 in (15.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.02 in (25.91 mm), catalogued under part number HS70312. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists petroleum oils and fuels, heat and oxidation, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) delivers improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. 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.

Typical settings include oilfield and downhole equipment, commercial refrigeration, and engine timing systems.

Order part number HS70312, sold individually. Nominal inside diameter is listed as 5/8 inch. Review your operating media and conditions against this specification before installation.
