-447 BROWN FKM 90D O-RING

Ordered as VB90447, this is an AS568-447 brown Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 8.975 in (227.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.525 in (241.94 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or hot water and steam.

You will find this material specified across semiconductor equipment, aerospace, and oil and gas.

This item is sold individually under part number VB90447. Nominal inside diameter is listed as 9 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
