3.53MM CS X 71.44MM ID BLACK FKM 75D

V3.53X71.44 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 71.44 mm (2.813 in), a cross section of 3.53 mm (0.139 in), and an outside diameter of 78.5 mm (3.09 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is widely chosen for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. It resists many acids, engine and transmission fluids, and aggressive chemicals. 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.

It sees regular use in oil and gas, aerospace, and automotive fuel systems.
