Moreover, we’ll give you our well-researched list of the 10 most popular grease guns on the market right now.

What Is A Grease Gun And What Are They Used For?

A grease gun is simply a tool used to apply grease or any other form of lubrication to the moving parts of machinery. Common in workshops as well as garages, the grease guns enable you to quickly apply the right amount of lubricant to a specific area, without making the place look messy.

What makes these tools ideal suitable for applying lubrication in the hard to reach areas of your machinery is the fact that they come with a tapered aperture or “nipple” that directs the grease to the desired area.

The grease gun finds extensive application in many fields involving the use of machinery that needs regular lubrication to reduce friction and run smoothly. Some of the key areas where a grease gun is used include:

  • Automobiles: to lubricate light-duty and heavy-duty trucks as well as the sports vehicles.
  • Agriculture: all those moving parts of a tractor and their implements require proper greasing…and there’s no better way to do it than with a grease gun.
  • Lubricating factory machinery components and equipment
  • Lubricating chainsaws and conveyors
  • Lawn mowers: if you want to improve the efficiency of your lawn mower, then consider lubricate its spindles with a grease gun
  • And so much more!

Types Of Grease Gun

We can classify the grease guns into 3 major categories depending on how they’re powered: hand, battery, and pneumatic/air powered.

The hand-powered models can further be subdivided into pistol grip, press, and lever style guns.

Let’s get a closer look at each type of grease guns:

types of grease gun

>Hand powered grease guns (with trigger mechanism)

Also referred to as pistol type grease gun (due to its pistol grip design), this gun style forces the grease out by back pressure that’s built up by the hand cranking its trigger mechanism.

The pressure is applied to a spring just behind the grease, which then forces the grease through the aperture/nipple and into the precise area where you want to apply it. These guns can deliver a pressure of around 3,500 to 10,000 psi, depending on the model.

A typical model can deliver as much as 0.86g of lubricant per stroke.

The biggest advantage of using this type of grease gun is that you can operate it with one hand, leaving the other one free to do other supportive tasks. Both lefties and right-handed users can operate it. And it comes in different sizes to fit different hand sizes.

>Hand powered grease guns (with press mechanism)

Also known as manual lever grease guns, these guns are also manually operated…but in a different manner. That is, you push on the butt of the gun by the mechanism of sliding a piston through the gun body. This will help built up back pressure which will then force the grease/lubricant out of the gun through the aperture.

Depending on which model you buy, you can find these grease guns with pressure ranging from 3,500 to 10,000 psi.

However, this type of hand pump grease gun isn’t the easiest to use.

>Battery powered grease guns

Grease guns that are powered by batteries are also referred to as cordless grease guns. These guns are loved because they eliminate the cord which can turn out to be a nuisance when using the grease gun.

Because of their power source, these models also save you from manually putting a lot of pressure to force out the lubricant. The guns also have the benefits of portability, where you can carry and use them to any place you want.

Most of the cordless grease guns you’ll find on the market today are rated between 6,000 and 10,000 psi.

>Pneumatic/Air powered grease guns

As the name suggests, grease guns that fall under this category are powered by air. In other words, they rely on compressed air which is fed to them via a hose. The compressed air then creates a pressure that forces the lubricant out so that you can direct it to where you want to apply it.

Given the fact that these guns need to be attached to the hose during operation, they can become inconvenient to some users.

Besides, they’re costly and are extremely powerful that they can end up blowing a bearing on the smaller machinery components. For this reason, pneumatic guns are confined to heavy-duty commercial and industrial applications.

How To Buy A Grease Gun?

Let’s face it… when shopping around for a grease gun, your end goal is to find  the best grease gun that allows you to easily apply the right amount of grease or any other lubricant on your specific type of machinery.

That being said, you’ll need to make the following considerations to ensure you find a model that matches your unique needs…

## Types of Grease Gun

One of the most important decisions you need to make when buying a grease gun is the type to choose.

As we discussed a bit earlier, the grease guns can be classified into various styles, depending on how they’re powered.

Let’s have a quick recap of these guns:

Lever: this is the cheapest and most popular type of grease on the market. It simply enables you to create pressure by pulling a lever. It’s suitable for light duty applications.

Pistol grip: easy to handle with only one hand. Available for both left- and right-handed users.

Cordless: powered by batteries. Portable and suitable for people who want a grease gun they can carry with them everywhere.

Hand pump: for this gun to apply the lubricant, your hand will need to do some pumping action

Pneumatic: the most powerful type of grease gun of all the above. Great for heavy-duty commercial and industrial applications.

## Ease of Use

The next thing you need to look for in a grease gun is how easy it is to use. You don’t want to buy a model that’s too complicated that it takes you forever to understand how it works.

The grease gun should easy to handle for you.

Most of the models we’ve discussed above also come with an extra-long flexible hose to make it easy for you to lubricate the hard to reach grease fittings, LED lights for easy greasing in low light situations, anti-slip rubber sleeve along the barrel for easy handling and cartridge changes, etc.

All these features make a grease gun easy to use for you.

## Amount of Lubrication

It’s also crucial that you know the quantity of lubricant you need to apply before buying a grease gun. Of course, this will depend on the type of machinery you intend to lubricate.

If your machinery needs high amounts of the lubricant for smooth running, then you should go for the high-volume grease guns. These models are able to dispense a high amount of grease per stroke for efficient lubrication of your machine moving parts.

For light duty applications, say around your home, then a standard grease gun with smaller capacity is sure to fit your needs.


Now that a grease gun is just another mechanical equipment that can break down unexpectedly, it’s also good to ensure you get one that comes with an extensive manufacturer warranty.

This way, you’ll have some peace of mind knowing that in case the tool fails, the manufacturer will repair or replace it for you without incurring any extra costs.

Benefits of Having The Best Grease Gun

Investing in the right grease gun comes with a number of benefits for anyone who relies on machinery and equipment that require regular lubrication.

Below are the FIVE distinct advantages of having a good grease gun:

1. No more lubricant wastage

The main reason why the grease gun has become so popular is that it allows you to measure the precise amount of oil or lubricant you’ll apply with every pull of the trigger. This is important in that it helps you use the accurate amount of lubricant and prevent wastage.

2. Proper lubrication

The gun’s ability to drive the lubricant right where it’s supposed to go is another reason why you should use this tool. It’ll allow you to get the right amount to the required area. And the direct result of proper lubrication is your machinery running smoothly and efficiently.

3. Extends your machinery life

When you do the lubrication properly, it’ll doubtlessly help reduce tear and wear between the parts of your machinery that grind over each other. It’ll make the bearings roll smoothly. All this drives away friction, enabling your machines to stay around for even longer.

4. Improves productivity

Yes, a grease gun will improve productivity around your workshop or garage. Compared to other lubrication methods, this tool is the easiest and fastest to use. It’ll enable you to grease all your machinery in a matter of minutes, saving you a great deal of time to focus on other important tasks.

5. Long-lasting

Lastly, a good grease gun is built with durable materials. Most of the top-rated models we’ve discussed in our list above are made using aluminum material for maximum strength while keeping the weight low. This means that this tool will serve you for a pretty long time (of course, you’ll have to take good care of it as explained in our next session).

How to Maintain A Grease Gun?

Being a mechanical tool, it goes without saying that your grease pump will need some regular care and maintenance to enable it to continue working well and serve you for an extended period of time.

In this section, we’ll share with you some crucial maintenance tips you should practice for maximum productivity of your grease gun:

  • Always make a point of testing your gun before using it to ensure it produces a smooth flow
  • Regularly inspect and thoroughly clean your gun fitting to eliminate any debris that might obstruct smooth flow
  • When not it in use, store your grease gun in a cool and dry place, and make sure you set in horizontal position. Consider covering it to keep it safe from dust and debris
  • Remember to always depressurize it after every use
  • DON’T use a different lubricant than the one you’re currently using. To avoid confusion, consider labeling the fitting with the type of lubricant in it.
  • Avoid placing your gun on dirty surfaces where it can easily collect and debris which can even get its fitting and affect its performance.
  • Regularly inspect your grease gun piping and immediately replaced damage and old looking hoses
  • Take precaution not to over pack your gun. Some models are capable of developing up to 15,000psi or more, which can result in seal damage

3. What types of lubricants can I use with a grease gun?

You can use any lubricant meant for lubricating your specific machinery. However, make sure you only feed your gun with high-quality lubricants that flow freely to prevent them from building up in the gun nozzle.

Also, avoid mixing up more than one lubricants in a single gun as this can significantly affect the effectiveness of the lubricants, making them less helpful to your machine. Where possible, we advise you to use dedicated guns for each lubricant.

If you’re only using one gun to apply different lubricants, make sure you completely purge and clean it before feeding it with the next grease to prevent contamination that can affect the grease performance.

4. How do I measure the output of my grease gun?

Different guns are designed to output different varying quantities of the lubricant. The amount of output for most guns range from 0.5 to 3g.

If you’re not sure how much your gun outputs, you can find out by pulling 10 consistent strokes into a calibrated scale and dividing the total value by 10. The result is the gun’s output per stroke.

Final verdict

No garage or workshop is complete without a good grease gun. This special tool has truly changed the way you lubricate the moving parts of your machinery and other equipment.
