Viton is generally compatible with hydrocarbons, but incompatible with ketones such as acetone, and organic acids such as acetic acid. O-rings made of Viton are typically color-coded as black, but new gaskets, seals and O-rings should be green FKM or black FKM, but with a green mark on the outer edge.iton fluoroelastomers are categorized under the ASTM D1418 and ISO 1629 designation of FKM.
Inorganic refers to a mineral that is made of compounds which are not organic. When something is inorganic, it has not arisen from natural growth.

Minerals are defined as naturally occurring, inorganic, solids with a definite chemical composition and a regular, internal crystalline structure. The keys to this definition are the chemical composition and the crystalline structure. Different chemical compositions result in different minerals.A good example is the mineral plagioclase.lbite has a chemical composition of NaAlSi. Different crystalline structures, or how the atoms and molecules are arranged, result in different minerals. A good example is diamond and graphite. Both minerals are composed of carbon (C).
