VB90123 is an AS568-123 brown Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 1.174 in (29.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.38 in (35.05 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. This material stands up to engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in chemical processing, automotive fuel systems, and aerospace.
