High-Performance Oil Delivers Superior Lubrication in High-Temperature, High-Load Applications

Duolec Industrial Gear Oil (1601-1610, 1302, 1304) is a high-performance industrial gear oil with ISO grades ranging from ISO VG 46 to 1500. Designed for use in any industrial gear or bearing application that requires a thermally stable, extreme pressure/antiscuff lubricant, it maintains performance even after filtration.

Duolec Industrial Gear Oil contains Duolec, LE’s dual acting additive that provides both wear-reducing and EP protection, and is fortified with a shear stable tackifier to provide adhesion to metal during use.

Beneficial Qualities

 N/A Maintains Performance in Extreme Conditions
  • Possesses high film strength
  • Remains stable despite high temps
  • Resists oxidation and sludge formation
  • Provides wear-reducing and EP/antiscuff protection
Adheres to Metal
  • Contains shear-stable tackifier that allows oil to adhere to metal components
  • Remains tacky during high shear use
Resists Moisture
  • Separates readily from water, continuing to provide effective lubrication
    • Ordinary gear oils will emulsify and foam, causing increased friction and poor lubrication
Filterable
  • Contains no solids that can be removed during filtration
  • Remains within viscosity grade after filtration

Proprietary Additives

 N/A LE’s proprietary additives are used exclusively in LE lubricants. Duolec® Vari-Purpose Gear Lubricant contains Duolec.

Duolec® dual-acting additive imparts synergistic properties to lubricants, providing both wear-reducing and extreme pressure protection. The result of revolutionary technology designed specifically for use in LE gear lubricants, Duolec increases oil film strength and is temperature activated to provide a protective layer that smooths metal surfaces and minimizes the effects of any contact, thereby reducing friction and preventing surface wear.
