-390 BLACK FKM 75D O-RING

V75390 is an AS568-390 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 20.953 in (532.21 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 21.373 in (542.87 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. This material stands up to petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

It sees regular use in semiconductor equipment, chemical processing, and aerospace.

V75390 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
