>...noise reduction in electronics...
The only other thing I found is it seems to be graphite in parafin, so probably used as a paint on electrical conductor, would be good for noise reduction (The IEEE article) and used for patching up flaky electrical contacts (another partial article). seems to date from the 50's or 60's ??
(There is a much older product named Carbon-X that is for removing carbon deposits in old automobile engines ...1912 vintage)
No one's pipe dies are interchangable , that would make sense....;P
But if you have a old Rigid threader it will probably fit.....
