-140 BROWN FKM 75D O-RING

Part number VB75140 is an AS568-140 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 2.237 in (56.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.443 in (62.05 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or hot water and steam.

Common environments for this compound include automotive fuel systems, chemical processing, and high-temperature process equipment.
