-416 BLACK FKM 90D O-RING

V90416 is an AS568-416 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 3.35 in (85.09 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.9 in (99.06 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to chlorinated solvents, many acids, and engine and transmission fluids. Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -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.

Maintenance and OEM teams specify it across high-temperature process equipment, oil and gas, and chemical processing.
