568-425 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70425, this is an AS568-425 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 4.475 in (113.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.025 in (127.64 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against heat and oxidation, sour gas and amine inhibitors, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving esters or strong oxidizing acids call for a different compound.

Common environments for this compound include oilfield and downhole equipment, engine timing systems, and automotive air conditioning.

This item is sold individually under part number HS70425. Nominal inside diameter is listed as 4 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
