This o-ring is supplied in AS568-369 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 7.975 in (202.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.395 in (213.23 mm), catalogued under part number V75369. It compresses into its gland to block fluid or gas migration across a joint.
As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. It resists engine and transmission fluids, aggressive chemicals, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.
You will find this material specified across aerospace, high-temperature process equipment, and chemical processing.
This item is sold individually under part number V75369. Nominal inside diameter is listed as 8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need?
