3.1MM CS X 59.4MM ID BLACK FKM 75D

Part number V3.1X59.4 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 59.4 mm (2.339 in), a cross section of 3.1 mm (0.122 in), and an outside diameter of 65.6 mm (2.58 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Supplementary detail from the product record: Metric O-RING, JIS G60.

The material holds up against aromatic hydrocarbons, aggressive chemicals, and chlorinated solvents. 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). It should not be specified for service in hot water and steam or ketones and esters.

Typical settings include chemical processing, automotive fuel systems, and semiconductor equipment.
