Phillips 66® GLW 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.
