Product Specification

-
This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 28 mm (1.102 in), a cross section of 6 mm (0.236 in), and an outside diameter of 40 mm (1.57 in), catalogued under part number H6X28. It compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Expect good resistance to greases and lubricants, hydraulic fluids, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or ozone and direct sunlight are present.

Common environments for this compound include construction equipment, fluid power, and general industrial maintenance.
