3MM CS X 91MM ID BLACK FKM 75D

Part number V3X91 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 91 mm (3.583 in), a cross section of 3 mm (0.118 in), and an outside diameter of 97 mm (3.82 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Viton® (FKM) is specified here for excellent resistance to compression set and permeation, industry benchmark where nitrile reaches its thermal limit. The material holds up against aromatic hydrocarbons, engine and transmission fluids, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

It sees regular use in semiconductor equipment, high-temperature process equipment, and automotive fuel systems.

V3X91 ships individually. Unit weight is approximately 3.8326 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
