EV-Silicon Oil-702

For diffusion pumps
EV-Silicon Oil-702 provides a drop in replacement for popular products such as DC 702, where ultimate vacuum and pumping speeds are of prime importance, it is an enhanced version that can obtain higher than normal pumping speeds.
Extensively used in heat treatment and investment casting applications where high auto-ignition temperatures are desirable. EV-Silicon Oil-702 provides exceptionally high resistance to oxidation and thermal stability when compared with mineral diffusion pump oils
