568-905 HSN90 DURO ORINGS

APG stocks the HSN90905, an AS568-905 green HNBR (Hydrogenated Nitrile) 90 Shore A O-Ring built to an inside diameter of 0.414 in (10.52 mm), a cross section of 0.072 in (1.83 mm), and an outside diameter of 0.558 in (14.17 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to heat and oxidation, modern refrigerants, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) delivers strong resistance to rapid gas decompression, excellent abrasion and tear strength. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C).

It sees regular use in heavy-duty powertrain, automotive air conditioning, and engine timing systems.

HSN90905 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
