Product Specification

-
H50002 is an AS568-002 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 0.042 in (1.07 mm), a cross section of 0.05 in (1.27 mm), and an outside diameter of 0.142 in (3.61 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

As a material, Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. It resists greases and lubricants, hydraulic fluids, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.

Common environments for this compound include agricultural equipment, hydraulic and pneumatic systems, and construction equipment.

This item is sold individually under part number H50002. Nominal inside diameter is listed as 3/64 inch. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
