Krytox™ XHT-500 is a specially engineered PFPE-based oil (500 cSt, 40°) for extreme high-temperature applications up to 572°F with NSF H1 certification.
Krytox™ XHT-500 Oil is a highly engineered perfluoropolyether (PFPE) based synthetic oil with low evaporation rates for extreme thermal stability and long-lasting lubrication performance. With a base oil viscosity of 500 cSt at 40°C, Krytox™ XHT-500 has an estimated useful temperature range of −20°C to 300°C (−4°F to 572°F).
Krytox™ XHT-500 is a nonflammable and completely nonreactive performance lubricant for incredibly harsh environments. Krytox™ XHT-500 meets food contact approval listed under NSF H-1.

Krytox™ XHT-500 Oil allows longer equipment shelf life and extends the lubrication interval for equipment. At temperatures above 300°C, it can begin to evaporate slowly. The rate at which the oil evaporates will increase as the temperature increases from 300°C. At these extreme temperatures, relubrication may be required to achieve optimum life.
Krytox™ oils can easily coat metallic surfaces with little or no adverse effects due to their low surface tensions and inertness. Testing metals at 300°C in the absence of air has shown little evidence of corrosion. In the presence of air, corrosion was slightly higher. The presence of molybdenum in the metals improved corrosion resistance. Extends equipment life and lubrication intervals Excellent wetting properties Nonreactive/Chemically inert Nonflammable Safe in oxygen or chemical service Incredibly high thermal stability (−4°C to 300°C)
Flammable or dangerous lubricating oil chemistry
Excessive oil loss in extreme high-temperature environments
Poor surface protection and lubrication from inferior oil technologies
Krytox™ XHT-500 is a high performance PFPE-base oil for a wide variety of specialty lubrication applications at high temperatures. The base oil will begin to slowly evaporate at temperatures exceeding 330°C and may require re-lubrication for optimum equipment life.
The Krytox™ XHT line of performance greases provide unrivaled thermal stability at extremely high temperatures. Explore how these highly engineered lubricants provide longer lasting protection and allow for extended equipment lifespan here.
