-445 BLACK FKM 90D O-RING

Part number V90445 is an AS568-445 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 7.975 in (202.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.525 in (216.54 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to many acids, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Typical settings include high-temperature process equipment, oil and gas, and chemical processing.
