The H90026 is an AS568-026 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 1.239 in (31.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.379 in (35.03 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists propane and butane, hydraulic fluids, and many alcohols. Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).
Typical settings include construction equipment, automotive, and hydraulic and pneumatic systems.
Stocked as H90026 and sold individually. Unit weight is approximately 0.3768 g. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
