-326 BLACK FKM 90D O-RING

Ordered as V90326, this is an AS568-326 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 1.6 in (40.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.02 in (51.31 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Common environments for this compound include oil and gas, semiconductor equipment, and high-temperature process equipment.
