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.

Overview

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.
