Krytox™ LVP Grease
Krytox™ LVP Grease is an NLGI Grade 2 PFPE grease with a fluorocarbon thickener for use in vacuum pumps with low vapor pressures and high contaminant control.
Krytox™ LVP is a high-vacuum grease with a PFPE base chemistry that provides premium performance over a broad range of temperatures and pressures. Krytox™ LVP is a highly reliable, low-friction lubricant that can be used in applications spanning from aerospace to electronics manufacturing and more. It has a viscosity of 740 cSt at 40°C and is completely nonflammable.
Krytox™ LVP high vacuum grease is formulated from a high-quality perfluoropolyether base oil that can withstand incredibly harsh conditions where mineral oil, hydrocarbon, and silicone-based greases fail.

Features & Benefits
Nonflammable Insoluble Chemically inert/Nonreactive Broad temperature range (−15°C to 30°C) NLGI 2 grease Excellent sealing properties
Problems Solved
Vacuum pump grease failure at extreme temperatures (low and high) Flammable or unsafe greases or oils Highly reactive greases or oils Buildup of solid deposits or byproducts in vacuum pump
Applications
Krytox™ LVP delivers proven performance and superior lubrication properties across a range of applications, including but not limited to the following:
Sealants and lubricants vacuum systems, High-temperature bearing, valve, and O-ring lubricants Pressure relief valve lubricants Oven conveyor chains and bearing greases Any lubrication requirement with high-temperature stability, low vapor pressure, or chemical inertness
Vacuum pump fluids are essential in a variety of specialty industrial processes, but are rarely thought about until something goes wrong. If you use a Krytox™ vacuum pump fluid, you may never have to think about the fluid again.
