-204 BLACK FKM 90D O-RING

The V90204 is an AS568-204 black Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 0.359 in (9.12 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.637 in (16.18 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Expect good resistance to petroleum oils and fuels, aggressive chemicals, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving amines or ketones and esters call for a different compound.

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