-443 BROWN FKM 90D O-RING

Part number VB90443 is an AS568-443 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 7.475 in (189.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.025 in (203.84 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with amines or hot water and steam.

You will find this material specified across automotive fuel systems, oil and gas, and chemical processing.
