Features and Benefits:

• Frequent oil changes will reduce vacuum pump failure and extend the pump life
• Thermally stable
• Laboratory tested resists breaking down
• High viscosity
• High viscosity Mastercool pump oil is engineered to maintain maximum viscosity to keep the pump operating at peak efficiency in any climate.

32 oz bottle of vacuum pump oil. Mastercool pump oil is engineered to maintain maximum viscosity to keep the pump operating at peak efficiency in any climate. Moisture, heat and other contaminants can quickly deteriorate the purity of the oil causing ineffiency during deep vacuum conditions.
