    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.
    2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.
    3 NLGI Grade—NLGI 3 is about the consistency of vegetable shortening and is comparable to Fomblin grease.
    3.5 NLGI Grade—NLGI 3.5 is between the consistency of vegetable shortening and frozen yogurt.
    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.

    Vacuum Pump Oil

    For long-lasting lubrication in vacuum pumps, this oil is slow to evaporate.
    Viscosity is the thickness of an oil. The higher the grade, the thicker the oil, and the less it flows.
