Purpose and Specifications

LIQUI MOLY Hydraulic Oil 1117 (HLP 46) is a premium 1-liter hydraulic fluid designed for heavy-duty systems in trucks, construction equipment, mining machines, and farm machinery. It delivers superior wear protection and maintains a strong lubrication film even under high loads and elevated temperatures up to 100°C, preventing metal-to-metal contact and extending component life.

This oil resists oxidation and corrosion, stays foam-free for smooth operation, and separates quickly from water, keeping your hydraulics reliable in wet conditions. It works safely with most seals, metals, and gaskets without causing swelling or damage. Neutral to common materials, it ensures long-term system cleanliness and performance from -25°C startup to high-heat operation.

• Volume: 1 liter tin container
• Standards: DIN 51524-2 HLP 46, DIN 5152
• Key Benefits: High thermal stability, excellent anti-wear additives, good demulsification

When to Use / Replace?

Use LIQUI MOLY 1117 in hydraulic systems with gears and bearings facing wide temperature swings or water exposure, like loaders, excavators, and tractors. Replace every 1,000-2,000 operating hours or 12-24 months under normal conditions, or sooner if operating in extreme heat above 80°C or dusty environments to avoid sludge buildup.

Shelf life is 5 years unopened when stored cool and dry. Check fluid level and condition monthly; dark color or milky appearance signals immediate replacement.
