568-384 HSN90 DURO ORINGS

APG stocks the HSN90384, an AS568-384 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 14.975 in (380.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 15.395 in (391.03 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, HNBR (Hydrogenated Nitrile) is specified for strong resistance to rapid gas decompression, excellent abrasion and tear strength. It resists modern refrigerants, ozone and weathering, and heat and oxidation. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Exposure to chlorinated hydrocarbons or esters will shorten service life.

Maintenance and OEM teams specify it across automotive air conditioning, oilfield and downhole equipment, and heavy-duty powertrain.

Reference part number HSN90384 when ordering; the item is sold individually. Nominal inside diameter is listed as 15 inch. Check the compound against your process media, pressure and temperature before committing to a design.
