VB75378 is an AS568-378 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 10.475 in (266.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.895 in (276.73 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

It sees regular use in automotive fuel systems, high-temperature process equipment, and aerospace.
