-903 BROWN FKM 90D O-RING

APG stocks the VB90903, an AS568-903 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 0.301 in (7.65 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.429 in (10.9 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is known for outstanding high-temperature capability, excellent resistance to compression set and permeation. This material stands up to aggressive chemicals, chlorinated solvents, and engine and transmission fluids. 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.

You will find this material specified across automotive fuel systems, aerospace, and high-temperature process equipment.
