Choosing the Right Grease

Every situation calls for a specific grease. What grease for bearings? Or for plumbing? What product should you use to lubricate the door hinges of your car? And honestly, what are all these technical terms for simple grease?
Let's clarify this together. You'll better understand why and how to effectively protect your installation with the right grease.

Understanding the Technical Characteristics of Grease

To choose the right grease, you first need to understand its technical characteristics.

First, do you need waterproof grease? If yes, then select grease that's insoluble in water and steam. Some can also withstand boiling water or seawater.

Oxidation deteriorates the quality of mechanical parts.
Don’t let your child's music box fall into disrepair; use the right grease.

What temperature range do you intend to use the grease at?
There are products that can withstand both high temperatures and high performance.

Will your grease be subjected to pressure? Or mechanical friction?

Adhesion is also an indispensable factor.
This is where the difference lies between quality grease and entry-level grease. Choosing the right grease protects your installation.

Does it need to be electrically conductive?
If so, we disclaim any liability for its use against your mother-in-law.

Are you planning to use it on rubber or plastic parts?
In that case, a specific grease should be selected.

It's possible for an oil to leak at a certain temperature.
This is known as the drop point.

Do you need a grease with high viscosity?
Remember that a fluid's resistance to flow varies with temperature. As temperature increases, viscosity decreases, and vice versa.

Is there ammonia present in your installation?
Some greases can handle this specificity.

Which Grease Should You Choose?

Among the most frequently used greases, graphite grease loosens mechanical assembly parts (such as screws, bolts, or nuts). It allows for both dry lubrication and good sealing. Even in a damp cellar, it will ensure that mechanical parts or the seals of a valve or tap are watertight without suffering from oxidation. It's also recognized for its high temperature resistance (800°C).
For low-temperature use, synthetic grease is ideal. You can use it to lubricate automotive accessories (sunroof slides, door hinges, locks, ...). It does not adversely affect plastic or rubber parts.
The silicone grease can be used for sanitary plumbing due to its long-lasting resistance and does not affect the pH (acidity) of water. This type of grease is suitable for indirect food contact.
There's also grease for food contact, to be used with food production and packaging machines. It resists water, pressure, and steam. You can use it to lubricate bearings, stops, gears, or even pivots.
However, for lubricating such equipment, the best option remains the bearing grease. It withstands extreme operating conditions (high temperature and high speed). Greasing intervals can be spaced out approximately 3 to 5 times.
If this frequency of greasing is too often for your installation, the multi-purpose grease allows for severe operating conditions while reducing greasing frequency.
The copper grease is electrically conductive and allows for non-destructive removal. It is perfect for bolting exposed to very high temperatures.
For the assembly of parts (bolts, threads, studs, ...) or for lubricating feed chains of furnaces, burners, or flue gas joint seals, consider the aluminum paste. It also prevents seizing and high-temperature corrosion.
