Product Specification

-
Part number H90206 is an AS568-206 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 0.484 in (12.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.762 in (19.35 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Expect good resistance to greases and lubricants, many alcohols, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.

Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and automotive.

H90206 ships individually. Unit weight is approximately 0.6573 g and nominal inside diameter is listed as 1/2 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.
