-404 BROWN FKM 90D O-RING

Part number VB90404 is an AS568-404 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 1.85 in (46.99 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.4 in (60.96 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists aggressive chemicals, engine and transmission fluids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit 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 low-molecular-weight organic acids or amines.

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

This item is sold individually under part number VB90404. Nominal inside diameter is listed as 1 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
