3MM CS X 79.5MM ID BLACK FKM 75D

Part number V3X79.5 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 79.5 mm (3.13 in), a cross section of 3 mm (0.118 in), and an outside diameter of 85.5 mm (3.37 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists many acids, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or hot water and steam will shorten service life.

Typical settings include semiconductor equipment, chemical processing, and high-temperature process equipment.

V3X79.5 ships individually. Unit weight is approximately 3.337 g. Check the compound against your process media, pressure and temperature before committing to a design.
