568-214 HSN90 DURO ORINGS

Ordered as HSN90214, this is an AS568-214 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring with an inside diameter of 0.984 in (24.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.262 in (32.05 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to modern refrigerants, ozone and weathering, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is specified for excellent abrasion and tear strength, long service life in refrigerant and oilfield duty. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). It is not the right choice where ketones or strong oxidizing acids are present.

Common environments for this compound include oilfield and downhole equipment, engine timing systems, and commercial refrigeration.

Stocked as HSN90214 and sold individually. Unit weight is approximately 1.169 g and nominal inside diameter is listed as 1 inch.
