568-377 HSN90 DURO ORINGS

Ordered as HSN90377, this is an AS568-377 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 9.975 in (253.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.395 in (264.03 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists ozone and weathering, petroleum oils and fuels, and modern refrigerants. HNBR (Hydrogenated Nitrile) offers strong resistance to rapid gas decompression, excellent abrasion and tear strength. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or strong oxidizing acids will shorten service life.

Common environments for this compound include oilfield and downhole equipment, commercial refrigeration, and heavy-duty powertrain.
