-910 BLACK FKM 90D O-RING

Ordered as V90910, this is an AS568-910 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 0.755 in (19.18 mm), a cross section of 0.097 in (2.46 mm), and an outside diameter of 0.949 in (24.1 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to petroleum oils and fuels, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or hot water and steam call for a different compound.

It sees regular use in aerospace, automotive fuel systems, and high-temperature process equipment.

Reference part number V90910 when ordering; the item is sold individually. Unit weight is approximately 0.0006 g and nominal inside diameter is listed as 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
