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.

1 Minerals Are Solid: substances that don't droop or melt or evaporate. 2  Minerals Are Inorganic: substances that aren't carbon compounds like those found in living things. 3  Minerals Are Crystalline: substances that have a distinct recipe and arrangement of atoms.rganic Minerals. The rule that minerals must be inorganic may be the strictest one. The substances that make up coal, for instance, are different kinds of hydrocarbon compounds derived from cell walls, wood, pollen and so on. These are called macerals instead of minerals (for more see Coal in a Nutshell).
