-464 BROWN FKM 90D O-RING

Part number VB90464 is an AS568-464 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. This material stands up to aromatic hydrocarbons, many acids, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or low-molecular-weight organic acids call for a different compound.

You will find this material specified across oil and gas, aerospace, and chemical processing.

VB90464 ships individually. Nominal inside diameter is listed as 17 1/2 inch. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
