DuoSeal pump oil comes in three different sizes: 1 liter(1407K-11), 1 gallon(1407K-15), and 5 gallon(1407K-20).
A specifically fractionated oil for DuoSeal belt-driven pumps is designed to ensure the highest vacuum performance. The oil is tested to high vacuum levels to meet rigid requirements for vapor pressure, vacuum level stability, and viscosity. DuoSeal vacuum pump oil is famous for its quality and consistency.
Pump oil can become contaminated with ingested fluids and vapors. Use recommended pump oil and change your pump oil regularly. Cloudy and discolored oil will lead to premature pump failure.
