Product Specification

-
Part number HS70377 is an AS568-377 green HNBR (Hydrogenated Nitrile) 70 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). An o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is specified here for strong resistance to rapid gas decompression, excellent abrasion and tear strength. Expect good resistance to sour gas and amine inhibitors, ozone and weathering, and petroleum oils and fuels. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Verify compatibility before use with esters or strong oxidizing acids.

Common environments for this compound include automotive air conditioning, engine timing systems, and heavy-duty powertrain.

Order part number HS70377, sold individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
