About Grease

About Lubricants

Seal and O-Ring Grease

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

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.

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.

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.

Stop Cock Grease

This thin grease goes on as a film to form a seal in glass and metal stop cocks.

Food Industry Seal and O-Ring Grease

This grease meets NSF/ANSI Standard 51 and FDA 21 CFR 175.300 for direct contact with food and NSF/ANSI Standard 61 for use with components that come into contact with drinking water.

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.

Grease

Moisture-Resistant Grease

Formulated to adhere to metal parts and stay in place in wet environments, this grease is commonly used in pulp and paper manufacturing and water management facilities.

Biodegradable Moisture-Resistant Grease

Protect equipment while having a limited impact on the environment. This grease resists moisture but still breaks down quickly in water.

Heavy Duty Moisture-Resistant Grease

Waterproof and heat-resistant, this grease can be autoclaved without washing out of equipment. It's chemically inert, so it won't interact with process fluids.

Long-Life Moisture-Resistant Grease

Nano-sized additives penetrate small surface imperfections, reducing wear and heat to extend the life of both the lubricant and equipment. It's formulated to adhere to metal parts and to stay in place in wet environments.

Petroleum Jelly

Brush on most metal surfaces to provide a layer of protection against corrosion.

Food Industry Petroleum Jelly

For use in food-processing and preparation areas, this petroleum jelly is NSF registered H1 for incidental food contact.

Grease

Use this general purpose grease to lubricate most machinery.

Biodegradable Grease

Protect equipment while limiting environmental impact. This grease breaks down quickly in water.

Lanolin

For use on metal parts to prevent corrosion and as an antiseize lubricant. Gauges are often coated in a thin layer of lanolin to move smoothly and maintain their precision.

Chemical-Resistant Grease

For use in applications where acids, bases, oxidizers, and fuels are present.

Food Industry Grease

For use in food-processing and preparation areas, this grease is rated for incidental contact with food.

Controlled-Use Food Industry Grease

This grease comes in cartridges that only work with our Controlled-Use Food-Grade Lever-Grip Grease Guns to make sure that the right grease is used in food-processing areas. It is NSF registered H1 for incidental food contact.

Clean Room Grease

Highly pure and with no additives to contaminate sensitive environments, use this grease in clean rooms and electronic assembly workstations.

Oil

Seal and O-Ring Oil

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

Food Industry Oil

Use this oil in food-processing and preparation areas.

Chemical-Resistant Oil

This oil is chemically inert and long lasting with an indefinite shelf life.

High-Pressure Oil

Use at pressures up to 50,000 psi.
