Seal and O-Ring Grease

Apply directly to seals and O-rings to extend service life by preventing drying and cracking.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter. Synthetic-oil-based grease lasts longer than mineral-oil-based grease and withstands a wider range of temperatures.
Grease with PTFE thickener has good heat, moisture, and oxidation resistance. Grease lubricates most efficiently within the listed temperature range. Chemours Krytox™ 240AC Type III resists most acids, bases, solvents, and fuels, and is long lasting with an indefinite shelf life.
High-Vacuum Seal and O-Ring Grease

A firm consistency and resistance to evaporation make this grease ideal for high-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.
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.
