-021 BROWN FKM 90D O-RING

Ordered as VB90021, this is an AS568-021 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 0.926 in (23.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.066 in (27.08 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to aggressive chemicals, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

Typical settings include automotive fuel systems, chemical processing, and semiconductor equipment.
