Seal and O-Ring Grease


Pail	Tube

Apply directly to seals and O-rings to extend service life by preventing drying and cracking.

Grease lubricates most efficiently within the listed temperature range.

Jet-Lube Ezy-Open Liquid—Jet-Lube Ezy-Open is a grease-like liquid that contains detergent and PTFE additives to clean more effectively than grease while it lubricates. Since it is a liquid, it does not have a NLGI viscosity grade, but is less viscous than anything else in our offering.

Krytox™ 240AC Type III—Chemours Krytox™ 240AC Type III resists most acids, bases, solvents, and fuels, and is long lasting with an indefinite shelf life.

Krytox™ RFE PFPE LB 8209—Loctite® Krytox™ RFE PFPE LB 8209 handles extreme temperature swings, resists acids, bases, and fuels, and is long lasting. It can be used under high loads.

Molykote 55 O-Ring Grease—DuPont Molykote 55 O-Ring Grease is silicone-based, so it can be used with most rubbers and plastics. Not recommended for use with silicone rubber, polycarbonate, or ABS.

Barium Thickener—Grease with barium thickener is for use with silicone rubber O-rings and seals in open systems.

Lithium Thickener—Grease with lithium thickener offers good heat and moisture resistance.

PTFE Thickener—Grease with PTFE thickener has good heat, moisture, and oxidation resistance.

Silica Thickener—Grease with silica thickener resists washing off and reduces corrosion in wet environments.

1 NLGI Grade—NLGI 1 is about the consistency of tomato paste.

2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.

Mineral Oil Base—Mineral-oil-based grease, derived from petroleum, is more economical than synthetic-oil-based grease.

Synthetic Oil Base—Synthetic-oil-based grease lasts longer than mineral-oil-based grease and withstands a wider range of temperatures.

Molybdenum Disulfide Additive—Grease with molybdenum disulfide has excellent resistance to wear and can withstand high-load and high-pressure applications.

PTFE Additive—Grease with PTFE has small particles of PTFE that reduce friction and help the grease maintain its lubricity.

Zinc Alloy Additive—Grease with zinc alloy neutralizes acid and is a good replacement for leaded grease.

Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Clean Room Seal and O-Ring Grease


Tube	Grease Gun Cartridge

Highly pure, this grease is chemically inert, so it won’t contaminate sensitive environments or react with other substances. Due to its low vapor pressure, it resists evaporation, even at high temperatures. Apply directly to seals and O-rings to prevent drying and cracking.

Grease lubricates most efficiently below the maximum temperature.

2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.

Nonmelting—Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.
