-026 BLACK BUNA 90D O-RING

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.
