MAROK®

ADHESIVE, EXTREME-PRESSURE LUBRICANT

Phillips 66® Marok® is a high-quality, adhesive, extreme-pressure (EP) lubricant specially developed to lubricate in the presence of moisture or where oil leakage is a problem. It is recommended for the lubrication of marine, mining, and industrial equipment operating in wet environments, and for the lubrication of air-powered tools, such as rock drills and jackhammers.

MAROK®

Features & Benefits

  • Good extreme-pressure properties
  • Protects against wear and seizure
  • Excellent adhesion to metal surfaces in the presence of moisture
  • Resists dripping and leakage
  • Protects against rust and corrosion
  • Low odor

Applications

  • Pneumatic percussion tools such as jackhammers, pavement breakers, and rock drills
  • Mining equipment such as demolition hammers, chipping hammers, and drifters
  • Marine applications such as stern tube bearings, oil-lubricated tunnel bearings, and cylinder lubricant for steam engines and crosshead engines
  • Drive chains and overhead conveyors where a non-drip lubricant is required
  • Enclosed industrial gear drives where oil leakage is a problem
