Premium High Vacuum Pump Oil, Quart Bottle

• Robinair's oil is engineered to maintain maximum viscosity at high running temperatures and to improve cold weather starts. • Laboratory tests prove that Robinair oil is more thermally stable in comparison to other leading brands, which means it resists breaking down due to heat for a longer period of time. • Robinair oil has a lower moisture content than other oils, thanks to our special packaging and handling procedures. • Moisture degrades the oil's purity, thinning it and reducing the pump's ability to reach a deep vacuum.
