3MM CS X 80MM ID BLACK FKM 75D

Part number V3X80 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 80 mm (3.15 in), a cross section of 3 mm (0.118 in), and an outside diameter of 86 mm (3.39 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The compound resists many acids, aromatic hydrocarbons, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

Maintenance and OEM teams specify it across chemical processing, aerospace, and automotive fuel systems.

V3X80 ships individually. Unit weight is approximately 3.3494 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
