4MM CS X 236MM ID BLACK FKM 75D

V4X236 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 236 mm (9.291 in), a cross section of 4 mm (0.157 in), and an outside diameter of 244 mm (9.61 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The compound resists aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. 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.

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