Compare base oils, thickeners, and additives to find the right grease for your application.
High-Vacuum Seal and O-Ring Grease
 |
Tube |
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.
Grease lubricates most efficiently below the maximum temperature.
Chemours—Chemours Krytox™ 240 grease is long lasting with an indefinite shelf life.
PTFE Thickener—Grease with PTFE thickener resists aggressive acids, bases, and solvents.
2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.
Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.
