    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.
    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.

    For use in food-processing and preparation areas, this oil is NSF registered H1 for incidental food contact. It’s slow to evaporate for long-lasting lubrication in vacuum pumps.
    Viscosity is the thickness of an oil. The higher the grade, the thicker the oil, and the less it flows.
