The V90451 is an AS568-451 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 10.975 in (278.77 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 11.525 in (292.74 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists aggressive chemicals, aromatic hydrocarbons, and many acids. Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.

It sees regular use in oil and gas, chemical processing, and aerospace.
