Ordered as HS70126, this is an AS568-126 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.
As a material, HNBR (Hydrogenated Nitrile) offers the oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. Expect good resistance to modern refrigerants, ozone and weathering, and heat and oxidation. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to strong oxidizing acids or ketones will shorten service life.
Maintenance and OEM teams specify it across automotive air conditioning, commercial refrigeration, and heavy-duty powertrain.
HS70126 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
