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 inefficiency during deep vacuum conditions.
Features:- Frequent oil changes will reduce vacuum pump failure and extend the pump life
- Thermally stable
- Laboratory tested resists breaking down
- High viscosity
