Vacuum Seal and O-Ring Grease
A firm consistency and resistance to evaporation make this grease ideal for vacuum applications, such as flow meters, vacuum and pressure systems, and laboratory equipment. Apply directly to seals and O-rings to prevent drying and cracking.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening and is comparable to Fomblin grease.
Grease with PTFE thickener resists aggressive acids, bases, and solvents. Chemours Krytox™ 240 grease is long lasting with an indefinite shelf life.
Grease lubricates most efficiently below the maximum temperature. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.
