4MM CS X 297MM ID BLACK FKM 75D

Part number V4X297 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 297 mm (11.693 in), a cross section of 4 mm (0.157 in), and an outside diameter of 305 mm (12.01 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against many acids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or hot water and steam call for a different compound.

Common environments for this compound include automotive fuel systems, oil and gas, and aerospace.

This item is sold individually under part number V4X297. Unit weight is approximately 21.655 g.
