Krytox™ XHT-1000 Oil is a special extreme high temperature grade oil with low evaporation and extra treatment to allow use at temperatures above the range of normal PFPE oils. Krytox™ XHT-1000 Oil has viscosity of 1023 cSt @40°C.
Krytox™ XHT-1000 Oil is a special extreme high temperature grade oil with low evaporation and extra treatment to allow use at temperatures above the range of normal perfluoropolyether (PFPE) oils. Krytox™ XHT-1000 Oil provides excellent lubrication over a broad temperature range. All Krytox™ XHT series oils are nonflammable and chemically inert.

Features & Benefits
Krytox™ XHT-1000 Oil allows for extended lubrication intervals and longer equipment life. The oil can begin to slowly evaporate at temperatures above 360°C, and this will occur at an increasing rate as temperatures increase. Re-lubrication could be required at these temperatures to achieve optimum life.
Due to their low surface tensions, Krytox™ oils easily wet metallic surfaces, and, because of their inertness, Krytox™ oils have little or no adverse effect on metals. Testing of metals at 340°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.
Krytox™ oils offer excellent stability, lubricity, and viscosity under a wide range of conditions. The product line includes linear oils, fluorescing oil, general-purpose lubrication, sintered bearing oils, and vacuum pump fluids, all of which combine high-temperature performance, non-flammability, and chemical inertness.
