This is a case where my transferable skills come in to help (well , not
really...).  Viton is a brand name owned by Dupont or Dow, (I forget which,
and I think they merged anyways)  There are at least 4 different groups of
Viton, probably more.  Viton can have carbon black or not.  I've seen it
light blue, pink, white, red-brown, and of course, black.  The only way you
can tell is by reading the label.  There are lots of Viton-like o-rings out
there.  Viton is good for it's high temp resistance, long shelf life, and
ability to deal with corrosive materials.  How do I know all this stuff?
Used to be a submarine mechanic.  We had to staple the o-ring packaging on
to our QA/QC work to ensure the proper o-ring was installed.  Soooo...don't
rely on color!
