568-260 HSN90 DURO ORINGS

Ordered as HSN90260, this is an AS568-260 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

As a material, HNBR (Hydrogenated Nitrile) offers improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. It resists modern refrigerants, petroleum oils and fuels, and sour gas and amine inhibitors. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to ketones or chlorinated hydrocarbons will shorten service life.

It sees regular use in heavy-duty powertrain, engine timing systems, and automotive air conditioning.

HSN90260 ships individually. Nominal inside diameter is listed as 6 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
