VacOil® 19 Grade is high viscosity vacuum pump oil designed for use with direct drive rotary vane pumps and is ideal for most general purpose applications. Its quality formula improves pumping cycles, lowers maintenance costs, cools pumps, and extends fluid life. 

VacOil® vacuum fluids are superior quality molecularly distilled vacuum pump oils engineered to perform and provide the ultimate protection from wear that causes pump repairs and pump failures. Lab tests reveal superior performance such as viscosity change and sediment weight when tested against competitive brand oils, outlasting and outperforming other vacuum oils.
