About Lubricants

About Grease

Tackier than gear box grease, this grease sticks to open gears and roller chain. It resists moisture for corrosion protection and can lubricate under heavy loads.

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

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

Grease with lithium thickener offers good heat and moisture resistance. Grease with asphalt thickener is thicker for excellent adhesion to chain and open gears. 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.

Food Industry Open Gear and Chain Grease

For use in food-processing and preparation areas, this grease is NSF registered H1 or meets FDA Compliant 21 CFR 178.3570 for incidental contact with food. It's tacky to stick to open gears and roller chain.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 3 is about the consistency of vegetable shortening.Synthetic-oil-based grease has longer-lasting performance than mineral-oil-based grease. Made with PTFE thickener, it has excellent heat and moisture resistance. It is best for low-speed, high-torque gears and chain.

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

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 3 is about the consistency of vegetable shortening and is comparable to Fomblin grease.

Grease with PTFE thickener resists aggressive acids, bases, and solvents.

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.

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.

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 3 is about the consistency of vegetable shortening.

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.

Electrical-Insulating Grease

Also known as dielectric grease, use insulating grease to lubricate and protect electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.

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

Dielectric strength measures the maximum voltage a grease can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

Grease lubricates most efficiently below the maximum temperature.

Molykote 5 Compound is for use on insulators, bushings, and high-current switches.
