Mark,
This is a fairly common request - especially for product that is
going into a pressurized vessel. (Submarines, airplanes etc.)
Seems mercury has a nasty habit of vaporizing under pressure.
Anyway, we went through the effort a few years ago to assure no
mercury is used in any materials we use - there were none. What
you have to watch for is the use of things that contain mercury like
thermometers.
