568-924 HSN90 DURO ORINGS

Ordered as HSN90924, this is an AS568-924 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 1.72 in (43.69 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.956 in (49.68 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, petroleum oils and fuels, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with esters or ketones.

Maintenance and OEM teams specify it across automotive air conditioning, heavy-duty powertrain, and engine timing systems.

Order part number HSN90924, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
