Product Specification

-
Ordered as HS70357, this is an AS568-357 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 5.475 in (139.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.895 in (149.73 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone and weathering, sour gas and amine inhibitors, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is specified for 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 ketones will shorten service life.

It sees regular use in automotive air conditioning, commercial refrigeration, and heavy-duty powertrain.

Stocked as HS70357 and sold individually. Nominal inside diameter is listed as 5 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
