About Lubricants

About Grease

About Oil

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

NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening. It is good for tight-tolerance plug valves and high-pressure seals.

Mineral-oil-based grease, derived from petroleum, is more economical than synthetic-oil-based grease. Synthetic-oil-based grease lasts longer than mineral-oil-based grease and withstands a wider range of temperatures.

Grease with lithium thickener offers good heat and moisture resistance. Grease with PTFE thickener has good heat, moisture, and oxidation resistance. Grease with silica thickener resists washing off and reduces corrosion in wet environments. Grease with barium thickener is for use with silicone rubber O-rings and seals in open systems.

Grease with moly (molybdenum disulfide) has excellent resistance to wear and can withstand high-load and high-pressure applications. Grease with PTFE has small particles of PTFE that reduce friction and help the grease maintain its lubricity. Grease with zinc neutralizes acid and is a good replacement for leaded grease.

Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

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

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.

Moisture-Resistant Seal and O-Ring Grease

Thickened with silica, this heavy grease clings to parts so it won't wash off in wet environments. Apply directly to plastic and rubber seals and O-rings to prevent drying and cracking.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 3 is about the consistency of vegetable shortening.

Grease lubricates most efficiently within the listed temperature range.

Vacuum Seal and O-Ring Grease

A firm consistency and resistance to evaporation make this grease ideal for 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.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening and is comparable to Fomblin grease. NLGI 4 is about the consistency of frozen yogurt.

Grease with PTFE thickener resists aggressive acids, bases, and solvents. Chemours Krytox™ 240 grease is long lasting with an indefinite shelf life.

Grease lubricates most efficiently below the maximum temperature. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

Chemical-Resistant Seal and O-Ring Grease

Fluorocarbon and fluorinated polymer thickeners add chemical resistance to this grease. It remains intact when exposed to water and most solvents and chemicals. Apply directly to plastic and rubber seals and O-rings to prevent drying and cracking.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening.

Grease with moly (molybdenum disulfide) has excellent resistance to wear and can withstand high-load and high-pressure applications. Grease with PTFE has small particles of PTFE that reduce friction and help the grease maintain its lubricity. It’s not for use with ketones, such as acetone and MEK.

Grease lubricates most efficiently within the listed temperature range. 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

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.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.

Grease lubricates most efficiently below the maximum temperature. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

Seal and O-Ring Oil

Apply directly to seals and O-rings to extend service life by preventing drying and cracking. This oil can be used with virtually any rubber polymer, including Buna-N and neoprene.

Viscosity is the thickness of an oil. Rated at 100,000 centistokes (cSt), this oil has the consistency of honey, so it stays in place.
