MOBIL DTE 26 ULTRA

MOBIL DTE 26 ULTRA oils are high-performance anti-wear hydraulic oils with extended oil life capabilities and have demonstrated up to 2 times longer oil drain intervals versus similar competitive oils. They meet the stringent requirements of hydraulic systems using high-pressure, high-output pumps as well as other hydraulic system components such as close clearance servo-valves and numerically controlled (NC) machine tools. The products exhibit outstanding oxidation and thermal stability allowing long oil life and reduced deposit formation in harsh conditions and with severe hydraulic systems using high-pressure, high-output pumps. The keep clean performance helps protect critical hydraulic system components from malfunction, such as tight tolerance servo and proportional valves found in many modern hydraulic systems.

Product Type: Hydraulic Oils

Application Area: Bearings, Gears, Hydraulic Applications, Numerically Controlled (NC) Machine Tools, Pump, Servo Valves

Features: Anti-Wear Properties, Corrosion Resistant, Good Thermal Stability, High Oxidation Stability, High Performance, Long Oil Life, Low Maintenance Cost
