MAROK®

ADHESIVE, EXTREME-PRESSURE LUBRICANT

Phillips 66® Marok is a premium adhesive, extreme-pressure (EP) lubricant designed for use in wet environments or applications where oil leakage is a problem. It is ideal for lubricating marine, mining, and industrial equipment, as well as air-powered tools like rock drills and jackhammers.

Formulated with naphthenic base oils and a specialized additive package, Marok delivers excellent protection for pneumatic percussion tools and equipment operating under wet conditions. It offers strong load-carrying capacity to prevent wear and seizure of sliding metal surfaces under heavy or shock loads. The lubricant adheres firmly to metal surfaces even in the presence of moisture, providing reliable rust and corrosion protection.

Marok resists dripping and leakage, making it ideal for applications with large bearing clearances or inadequate seals.
