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.

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.

Assembly Lubricants for Rubber and Plastic

For hoses and other tight-fitting parts, apply these lubricants to rubber or plastic before assembling and disassembling. After drying, they lose their lubricity, so parts stay together. They leave no residue on assembled parts.

Semisynthetic-oil-based lubricants are a mix of synthetic and vegetable oil and are compatible with most plastic and rubber. They’re frequently used with hoses, O-rings, seals, and rubber grips. Vegetable-oil-based lubricants are designed for use with polyurethane and vinyl conveyor roller covers.

Food Industry Assembly Lubricants

For use in food-processing and preparation areas, these lubricants are rated for incidental food contact. Coat tight-fitting parts with them before sliding together to make assembly easier.

Mineral-oil-based lubricants have a high load-carrying capacity and can lubricate sliding loads at low-to-medium speeds. Synthetic-oil-based lubricants have excellent moisture resistance.

Assembly Lubricants

Coat tight-fitting metal parts, such as gears, clutches, and press-fit assemblies, with these lubricants before sliding them together to make assembly easier. Once assembled, they provide initial lubrication in equipment before oil has a chance to flow.

Mineral-oil-based lubricants, derived from petroleum, are more economical than synthetic-oil-based lubricants. Synthetic-oil-based lubricants last longer than mineral-oil-based lubricants.

Lubricants with moly (molybdenum disulfide) withstand high-pressure applications and have excellent wear resistance. Lubricants with graphite have additional pressure resistance and excellent temperature resistance. Lubricants with zinc prevent corrosion.

All Dupont Molykote lubricants have a high load-carrying capacity. Molykote M-77 Paste is commonly used on brakes and clutches; it is compatible with material that is damaged by mineral oil, such as natural rubber, SBR, and EPDM. As a paste it lubricates to 445° F; after drying, it continues to lubricate at temperatures up to 660° F. Molykote G-Rapid Plus Paste is often used to assemble threaded spindles, gears, screws, and pumps. It can be used as an initial lubricant. Molykote DX Paste has good corrosion resistance. It provides long-lasting lubrication after assembly.

Lubriplate No. 105 is often used to assemble motor and engine components. It has excellent moisture resistance.
