Severe-Duty, Extreme-Pressure Industrial Gear Oil

Phillips 66®GLW-E is a premium quality, extreme-pressure (EP) industrial gear oil developed for the lubrication of heavily loaded enclosed gear drives operating in wet environments under severe service conditions. It is specially formulated to emulsify readily with water to maintain effective lubrication in the presence of water. It is particularly recommended for use in industrial and mining equipment operating in a highly contaminated, wet environment where an emulsifiable AGMA EP gear oil is specified or preferred.

Features & Benefits

• Excellent performance in wet or contaminated gearboxes

• Outstanding load-carrying capacity

• Excellent protection against scuffing and wear

• Good oxidation resistance and thermal stability

• Outstanding deposit control for gearbox cleanliness

• Protects against rust and corrosion

• Emulsifies readily with water

• Good seal compatibility

• Environmentally responsible; does not contain chlorinated paraffins


• Enclosed gear drives of longwall mining machinery

• Enclosed industrial gear drives operating in the presence of water, such as in steel mills and rock quarries

• Gear drives and pinion stands of metal rolling mills, ball mills and cement mills

• Enclosed gear drives on excavation and heavy construction equipment
