Duolec Industrial Gear Oil from Lubrication Engineers

High-performance gear oil designed specifically for use in gearbox applications.


Today’s gearboxes have gotten smaller, yet they are expected to do more under conditions of high heat and heavy loads; and in solution with dirt, process debris and water.

Without adequate protection, the gears will wear prematurely. You’ll have to replace parts more frequently, change oil more frequently, and worst of all, you’ll experience equipment downtime. The answer is a high-quality gear oil that works hard for you 24/7, 365 days a year.

Duolec Industrial Gear Oil from Lubrication Engineers is a high-performance gear oil designed specifically for use in gearbox applications and known for its tenacious, metal-clinging, gear-climbing action. It is available in ISO viscosity grades ranging from 46 to 1,500.

Long-lasting Duolec Industrial Gear Oil remains thermally stable during use, and resists oxidation and sludge formation. Its extreme pressure properties allow it to combat heavy loads. Throughout its extended service life – even in extreme conditions – Duolec Industrial Gear Oil maintains film strength and viscosity. It also maintains tackiness, allowing it to cling to metal components. It separates readily from water, and it contains no solids that can be removed during filtration.

The secret to Duolec Industrial Gear oil is LE’s proprietary additive technology of the same name. When heavy loads and high speeds create heat, the Duolec liquid additive is activated, working in stages to provide a dual layer of anti-wear and extreme pressure protection. Duolec enhances the surface protection of the lubricant, preventing oil film rupture and reducing friction.
