Equivalent Brand: Dow Corning 702

Diffusion Pump Oil RJ-272 is a kind of general-purpose oil designed for fast pumping of large volumes of gas. It is used to produce vacuums in the range of 10 to 10 torr. It possesses excellent heat-stability, good resistance to oxidation and radiation. Its vapour pressure is very low under room temperature, and changes sharply with the variation of temperature.
