ArChine Diffutech 704

Vacuum Diffusion Pump Oil

Production Description:

Chemical structure:

Equivalent Brand: DOW Corning 704, MT-704, HIVAC-F-4

ArChine Diffutech 704 oil is a colorless to light yellow transparent oily, single-component fluid designed for high vacuum of 10^-7 torr (untrapped). It performs well in tough, rugged applications and offers quick pumpdown, even after exposure to air operating temperatures. ArChine Diffutech 704 is thermally and chemically stable allowing it to keep pump jets free of tars and hard carbon.
