TMC 19 and TMC 20 hydrocarbon pump oils are laboratory tested and proven to be superior to many other competitive brands. TMC 19 hydrocarbon oil offers superior molecular weight, higher viscosity index, and higher purity to perform reliably in many high vacuum environments.

TMC 704 diffusion pump fluid is a single component, tetramethyl tetraphenyl trisiloxane, clear fluid that is chemically equivalent to Dow Corning® DC-704. Developed for use in high vacuums of 10-6 Torr (untrapped) and 10-8 (trapped), TMC 704 performs well in tough, rugged applications with quick pump-down, even after exposure to air at high temperatures. It is thermally and chemically stable, which keeps pump jets free of tars, hard carbon and crystallization.
