Product Specification

-
VB90366 is an AS568-366 brown Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 7.225 in (183.52 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.645 in (194.18 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists chlorinated solvents, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) is specified for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

It sees regular use in automotive fuel systems, semiconductor equipment, and oil and gas.

VB90366 ships individually. Nominal inside diameter is listed as 7 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
