    High-Vacuum Seal and O-Ring Grease

    Image of Product. Front orientation. Grease. High-Vacuum Seal and O-Ring Grease, Tube.

    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.
    1 NLGI Grade—NLGI 1 is about the consistency of tomato paste.
    Nonmelting—Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.
    Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.
