LE Duolec Industrial Gear Oil ISO68
LE Duolec® Industrial Gear Oil (1601–1610, 1302, 1304) is a high-performance industrial gear oil available in ISO grades from ISO VG 46 to 1500. Designed for any industrial gear or bearing application that requires a thermally stable, extreme pressure/antiscuff lubricant, it maintains performance even after filtration. It 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.
