1.6MM CS X 18.1MM ID BLACK FKM 75D

Part number V1.6X18.1 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 18.1 mm (0.713 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 21.3 mm (0.84 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against chlorinated solvents, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for excellent resistance to compression set and permeation, 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).

Typical settings include automotive fuel systems, chemical processing, and high-temperature process equipment.
