This o-ring is supplied in AS568-419 black Viton® (FKM) 75 Shore A supplied with an inside diameter of 3.725 in (94.62 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.275 in (108.59 mm), catalogued under part number V70419. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists engine and transmission fluids, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

You will find this material specified across high-temperature process equipment, aerospace, and automotive fuel systems.
