    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.
    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.
