5MM CS X 18MM ID BLACK FKM 75D

Part number V5X18 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 18 mm (0.709 in), a cross section of 5 mm (0.197 in), and an outside diameter of 28 mm (1.1 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. It resists petroleum oils and fuels, many acids, and aromatic hydrocarbons. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to low-molecular-weight organic acids or amines will shorten service life.

You will find this material specified across chemical processing, aerospace, and oil and gas.
