Krytox PFPE Greases

DuPont Krytox Greases

Krytox greases, using the most advanced lubricant formulated from space-age fluoropolymer technology — are created by thickening synthetic perfluoropolyether (PFPE) base oils with micro-fine polytetrafluoroethylene (PTFE) powder, creating a white, nontoxic grease that provides excellent lubrication in demanding applications. The PTFE thickener forms a barrier that holds the base oil at friction contact points for long-term lubrication without requiring complicated oil recirculation systems.


Oxygen-safe Krytox oils and greases combine stability, high-temperature performance, non-flammability, and chemical inertness with outstanding lubrication under a variety of conditions.

  • General Purpose (GPL)
    Krytox™ GPL Greases deliver performance. When compared to other lubricants, only Krytox™ GPL greases combine stability, high-temperature performance, non flammability, and chemical inertness with outstanding lubrication under a variety of conditions.
  • Aviation / Aerospace
    Krytox™ lubricants were initially developed by DuPont in the early 1960s specifically for the precise and demanding lubrication needs of the aerospace industry. Krytox™ synthetic lubricants have since replaced hundreds of special-formula, hydrocarbon-based oils and greases throughout the aerospace and aviation industries.
  • Corrugator 226 / 227 FG
    Krytox™ Corrugator FG are H-1 certified, food grade greases designed to deliver superior performance with advanced features of high-temperature stability, non flammability, and chemical and biological inertness. Krytox™ lubricants will not carbonize or form gummy deposits that typically cause failures, nor will they evaporate. Therefore, maintenance cycles are extended and costs are significantly reduced.
  • Electronics Grade (EG)
    Krytox™ Electronics Grade (EG) greases are made from base oils with lower volatility compared to those used in the GPL series. It is important in the electronics industry to not have volatile products vaporize off and deposit themselves on other equipment.
  • Extra-High Temperature (XHT)
    Krytox™ XHT greases are designed for applications in the 400-750° F temperature range for use in bearings, gears, chains, o-rings, sliding, and other high-temp. mechanical components. These products are excellent for use in many harsh industrial applications and are currently used in Mining, Metal Processing, Power Generation, Textile, Aviation, Baking, and Chemical applications.
  • High Vacuum Grease (LVP)
    Low vacuum pressures. Extremely high or low temperatures. Hostile environments. Whatever special needs your system might have, Krytox™ low vapor pressure (LVP) high-vacuum grease works—safely, reliably, and cost-effectively. LVP high-vacuum grease performs over extremes of temperature and pressure that hydrocarbon, silicone, and chlorofluorocarbon greases can’t match. From –15–300°C (0–570°F), at vapor pressures as low as 10–13 mmHg, and in even the most chemically severe environments, Krytox™ LVP grease gives dependable, proven performance.
  • Thread Sealant
    Krytox™ TS4 Thread Sealant is unlike PTFE tape, which should be removed before re-application. Krytox TS4 can be re-applied over existing Krytox thread sealant. It clings to threads and will not shred or tear on assembly/disassembly. It won't plug or restrict critical piping, valves, or instruments like tape solids. Krytox TS4 is non-reactive, non-toxic, non-flammable, non-corrosive and compatible with most seal, O-ring, and valve polymers. No VOC content or hydrocarbon is in the product and is safe for oxygen use. It lubricates the threads, preventing costly thread damage from galling and seizing during assembly and allows low breakaway torque for easy-to-break connections.
