HSN (HNBR) 80 568-310

This o-ring is supplied in AS568-310 green HNBR (Hydrogenated Nitrile) 80 Shore A built to an inside diameter of 0.475 in (12.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.895 in (22.73 mm), catalogued under part number HSN80310. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against modern refrigerants, ozone and weathering, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, excellent abrasion and tear strength. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to esters or strong oxidizing acids will shorten service life.

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

This item is sold individually under part number HSN80310. 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.
