Designed to meet the rigorous performance standards of a wide range of hydraulic system and component manufacturers, Mobil DTE 21 is a high-performance anti-wear hydraulic oil for use with high-pressure, high-output pumps as well as components such as close-clearance servo-valves and numerically controlled (NC) machine tools. Mobil DTE 21 is ISO velocity grade 10. This product’s exceptional oxidation stability and remarkable anti-wear and anti-corrosion protection outperforms conventional products in safeguarding hydraulic systems from deposit and sludge formation. Mobil DTE 21’s controlled demulsibility also protects systems from small or large quantities of water. It can be effectively used in systems employing a wide range of components using various metallurgies, under severe service conditions and extended drain intervals. Mobil DTE 21 also helps prevent thin oil-film corrosion, even in systems requiring a high load-carrying capability.
