-344 BROWN FKM 90D O-RING

VB90344 is an AS568-344 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) delivers long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Expect good resistance to aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

You will find this material specified across high-temperature process equipment, chemical processing, and semiconductor equipment.
