-449 BLACK FKM 90D O-RING

The V90449 is an AS568-449 black Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 9.975 in (253.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 10.525 in (267.34 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists petroleum oils and fuels, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across chemical processing, aerospace, and semiconductor equipment.

Stocked as V90449 and sold individually. Unit weight is approximately 57.4 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
