-279 BROWN FKM 90D O-RING

VB90279 is an AS568-279 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 12.984 in (329.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 13.262 in (336.85 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to many acids, engine and transmission fluids, and aggressive chemicals. 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. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

Common environments for this compound include high-temperature process equipment, automotive fuel systems, and chemical processing.

This item is sold individually under part number VB90279. Nominal inside diameter is listed as 13 inch. Check the compound against your process media, pressure and temperature before committing to a design.
