Overview of McLube Grease

McGee Industries has manufactured greases for over sixty years and currently offers a diverse line of NLGI #2 greases with varying attributes to suit individual needs. We offer specialized greases for specific industrial manufacturing operations as well as lubricant greases for general-purpose application. McLube Grease is fortified with molybdenum disulfide or boron nitrate for enhanced secondary lubrication and extreme pressure and temperature tolerances. We provide environmentally-conscious greases that do not contain heavy metals or other harmful additives like phosphorus, chlorine, zinc, phenols, antimony, barium or lead. Our Moly greases are proven to reduce wear and prevent the galling of parts, threads and gears for metal-metal and metal-composite interactions.


McLube Technical Representatives will recommend one of our cost-effective greases based on temperature, pressure and degree of movement at the application site. Applications with a high degree of movement will require McLube Greases with the highest concentrations of lubricating additives like molybdenum disulfide to ensure long-lasting wear prevention. Explore below for more information about McLube Greases or contact us for technical assistance.

General Application Grease

-40 to 760°F (-4 to 405°C)

McLube’s general-purpose greases are lithium-based NLGI #2 lubricants fortified with molybdenum disulfide. Molybdenum disulfide (MoS2) enhances the slip characteristics of the base grease and improves the temperature and pressure tolerances of the lubricating formula. Greases are applied to prevent seizure and wearing, but movement will inevitably cause the grease to migrate from the application site and become ineffective. MoS2-fortified greases will last longer than conventional alternatives because of the secondary lubricating qualities of the MoS2 additives. MoS2 will remain at the application site after the base grease has been worked out and continue to provide excellent lubricating qualities. Reducing the need for reapplication makes these greases ideal for applications involving a high degree of movement or for hard-to-reach areas where reapplication slows down operations. Our general-purpose greases will remain effective under pressures as high as 250,000 PSI and temperatures in excess of 760°F (404.44°C).



McLube Technical Representatives will recommend one of our greases based on temperature and the appropriate MoSconcentration for your application.  Concentrations of MoS2 will increase with degree of movement and pressure at the application site to maintain effective lubrication.

High-temperature Greases

760 to 1,100°F (405 to 594°C)

McLube Greases for high-temperature applications are NLGI #2 lithium-based lubricants fortified with the highest concentrations of molybdenum disulfide. McLube also offers high-temperature greases with boron nitride and graphite additives. Boron nitride additives will enhance the chemical and thermal resistance of the base grease for use in extreme environments like metal forging and ceramics manufacturing. Boron nitride’s chemical resistance allows for excellent slip characteristics on even the most corrosive and chemically abrasive compounds. McLube also offers customized graphite-fortified greases for enhanced thermal resistance. Contact McLube for product details and technical assistance with high-temperature applications.

Benefits of McLube High-Temperature Greases

  • Reduced wear and galling in extreme conditions
  • Pressure tolerance up to 250,000 PSI
  • Ideal for metal forging lubrication
  • Suitable for use on high-pressure threading, seals, and gaskets
  • Protect surfaces from rust and corrosion

McLube Aerosolized Grease

McLube offers NLGI #2 lithium grease fortified with molybdenum disulfide in ready-to-use aerosol cans. Our convenient aerosolized grease is ideal for hard-to-reach applications and will dramatically reduce downtime for lubricating steps. Molybdenum disulfide acts as both secondary lubricant and fortifying compound. Molybdenum disulfide’s low coefficient of friction (degree of lubricity) enhances the lubricating qualities of the base grease and will continue to offer excellent slip characteristics after the lithium base migrates or volatilizes under extreme conditions. While our aerosolized greases were designed for superior lubrication, many customers use these products solely for rust prevention on high-stress, high-tension threads, bolts, nuts, and gaskets where frequent re-calibration is required.


Benefits of McLube Aerosolized Grease

  • Ideal for high-tension, extreme temperature applications
  • Non-dripping, will not run off applied surface
  • Superior EP and wear resistance
  • Excellent surface penetration

Common Applications

Plain bearings, threaded connections, press fittings, bicycle chains, anchor bolts, hex nuts, studs, sliding surfaces, gaskets, open gears, general lubrication, etc.

Fracking and Drilling Grease



McLube offers tailor-made greases for the oil and gas industry. McLube Greases are all NLGI#2-grade and fortified with Molybdenum Disulfide for secondary lubrication and enhanced temperature and pressure tolerances. Continue reading for more information or contact McLube directly for pricing, safety data sheets, and samples.


McLube Greases fortified with molybdenum disulfide are ideal for high-pressure, high-temperature applications like fracking and oil drilling operations. Molybdenum disulfide acts as both secondary lubricant and fortifying compound, ensuring your McLube Grease remains effective after extreme heat and pressure cause the base to volatilize or migrate. The highest concentrations of MoS2 fortifications will provide heat tolerance as high as 1,100°F and pressure tolerances in excess of 250,000 PSI. McLube technical representatives can help you select the ideal MoS2 concentration for your operation. Contact McLube for assistance and free samples.


McLube NLGI#2-based greases offer excellent lubricating properties while also preventing rust and corrosion. The NLGI#2 base is also an effective water-resistance sealer. Our greases resist migration from the original application site to cut down on the frequency of reapplication.


Units: 35-lb pail, 400-lb drum, 1400-lb tote
