-266 BROWN FKM 90D O-RING

Part number VB90266 is an AS568-266 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 7.984 in (202.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.262 in (209.85 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to chlorinated solvents, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in automotive fuel systems, aerospace, and high-temperature process equipment.
