4MM CS X 370MM ID BLACK FKM 75D

The V4X370 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 370 mm (14.567 in), a cross section of 4 mm (0.157 in), and an outside diameter of 378 mm (14.88 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists aggressive chemicals, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or hot water and steam.

You will find this material specified across high-temperature process equipment, aerospace, and oil and gas.
