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.

TMC 705 diffusion pump fluid is a single component (Pentaphenyl trimethyl trisiloxane), clear fluid that is chemically equivalent to Dow Corning® DC-705. Developed for use in ultra-high vacuums of 10-9 Torr (untrapped) and 10-11 (trapped), TMC 705 performs well in high purity metalizing applications where quick pump-down is needed, as well as thermal, radiation and chemical stability.

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 Y06/6 PFPE Virgin vacuum pump fluid sold in bulk by the pound (lb.). Among the many features, this PFPE oil is non-flammable, thermally stable, radioactively stable, has high dielectric properties, and performs in both high and low temperatures. The presence of fluorine in this oil provides thermal, chemical, and oxidative stability. The presence of oxygen provides imparted flexibility to the polymer chain, excellent flow behavior at low temperatures, and a high viscosity index for linear PFPEs. Due to its chemical inertness it is compatible with plastic, metal, and elastomers, and along with a low miscibility with solvents and water.
