No mechanic’s arsenal is ever complete without a good pneumatic grease gun. Useful when it comes to lubricating certain objects and machinery pieces, the best pneumatic grease gun is perfect when it comes to DIY projects – but also for maintenance around the house. They are very efficient for a variety of tasks, ensuring that the bearing and the nuts fit properly.
These pneumatic grease guns are sold in a variety of shapes and sizes. From air-pressured to hand-pumped guns, you have a wide variety of items to pick from. It can be rather stressful to choose the proper one – which is why we took it upon ourselves to bring you the information that you need. Here are some pneumatic grease gun reviews that you might find useful.
Benefits of a Pneumatic Grease Gun
Workshops or garages are not complete until you add a pneumatic grease gun in the mix as well. Its purpose is to use pistons and compressed air to shoot grease from a nozzle into a specific location.
Each kind of grease gun is efficient in its own way. However, there are certain things that make the pneumatic grease gun a more user-friendly option. Here is why you might want to consider investing in such a unit.
1. It Prevents Waste
At some point, you might want to consider using oil, grease, or any kind of lubricant in your garage – no matter if it’s on a vehicle or on anything else. Normally, people can easily apply that lubricant without any kind of tool – but with a pneumatic grease gun, the application will be much more precise. Each time you pull the trigger, you will have the exact amount of grease, exactly where you need it.
This is highly important for one and one reason only: waste. Each time you use your hands to apply that grease, you will undoubtedly use more grease than you actually need. Not only will this cause things to become much messier – but it will cause you to run out of grease far ahead of its time.
The opposite may also happen: without a grease gun, you may end up using too little grease – in which case, your pieces will not be lubricated properly. The grease gun will ensure that the amount you use is actually the perfect one for your situation.
2. It Saves You Time
When you are in a workshop or working with a vehicle, time is of the essence. However, when you have so many parts that need to be lubricated, this “time” may take more than it normally should if you decided to use the “just hands” method.
However, with a pneumatic grease gun, you should be able to grease the whole underside of a car in just one minute or less. This is a great solution if you have more than one vehicle to grease that day – which is why it is also a great choice if you are working at a shop and are pressed by time.
3. It Gives You Perfect Application
If you want to properly maintain the life of a vehicle along with its components, you have to get that grease exactly where it is needed. Other grease devices might simply disperse the lubricant over the area, messily spraying a shot.
However, a pneumatic grease gun permits the grease to get right into the area, exactly where you need it. Once you press the trigger, the gun will force the grease through the nozzle and push it straight into the area where you need it – and not in the general direction.
4. It Has a Long Lifespan
Perhaps one of the main advantages of a pneumatic grease gun is the fact that it has a longer life compared to other types of grease guns. Since these grease guns have more durable parts made from quality materials, they can last you for more than ten years under continuous use. It may be an investment, but at least you will know for certain that you will not have to buy a new one anytime soon.

Types of Grease Guns
Grease guns are sold in various shapes and sizes. Here are the most common types of pneumatic grease guns that might be up to your interest.
1. Manual Lever Grease Gun
When it comes to pneumatic grease guns, the lever operated kind is likely the most popular option to go for. You may easily apply grease by simply pulling on the lever, which will create enough pressure for the grease to be automatically pushed out.
You may adjust the amount of grease you push out by the way in which you touch and press the lever. However, considering that lever grease tools are rather mechanical units, you will have to use both of your hands to keep it stabilized and in the precise point.
2. Manual Pistol Grip Grease Guns
A grease gun that has been operated by a pistol will likely improve your control as it can be used with only one hand as well. Since the grip of the handle can be bought in various sizes, you may easily choose the one with which you feel most at ease.
Different from the lever kind, this one does not require you to vary the length of the lever to adjust the amount of grease. The pistol grip will apply pressure to the trigger – therefore pushing the grease. All you will have to do is point the nozzle in the right direction.
3. Pneumatic Hand Pump / Hand Grip Grease Gun
A hand pump grease gun will work slightly different compared to a pistol-grip gun or a lever gun – mainly because this one involves the operation of a pump. It produces a sufficient amount of pressure that is needed to push the grease out of the nozzle – and it works by building up the air and directing it into the gun.
Some find it slightly more difficult to position this kind of gun compared to the other types. However, if you have already been using pumping tools with just one hand, mastering the technique, then you may have no issues using this kind of gun.
4. Cordless Grease Gun
If you like having a certain degree of freedom of movement, then a cordless unit may be exactly what you should be looking for. Not only does it allow you to properly move around, but it also offers you more precision while you are doing your task.
Since there will not be any cord dangling around, it should be much easier for you to adjust the grease gun. You can apply the lubrication wherever you need it, without worrying that you will accidentally trip over the cord.
These grease guns are powered by a battery, which means that they have limited running power and they will have to be recharged. However, they provide consistent pressure, which means they should be very efficient in any task.
5. Air-Powered Pneumatic Grease Guns
Air-powered pneumatic grease guns are more suitable when it comes to commercial use – and they are taken out whenever the types above cannot handle a job. They are used mostly for large-scale projects that require the use of a heavy-duty tool. As a result, most of the air-powered units will be high-pressure tools that will make use of an air compressor through a hose.
Needless to say, an air-powered grease gun will have a pretty hefty price tag. Bear in mind that only experienced personnel should be allowed to use it – and ideally, with help. Operating alone or with no experience may lead to some great damage to the seals and the bearing shields. In some circumstances, it may even lead towards the winding of the electric motor, as well as some other environmental safety hazards.
What Is a Pneumatic Grease Gun?
A pneumatic grease gun is an air-powered tool that is used to apply lubricants (namely, grease) to certain areas, with the purpose of maintenance or for certain DIY projects. This grease is generally most useful when it comes to metal, where you have to use bearings and bolds.
This kind of lubricant is necessary for ensuring that the components in the anatomy of a certain unit will slide efficiently together. It is also necessary for ensuring that the quality of a metal, in particular, is maintained properly.
The grease is usually delivered by using the force of pressure from a gun. Each part of the grease gun works to deliver that proper power, from its housing to the grease tube, the grease cartridge, the pump, and the hydraulic connectors. You will find out more about those parts later on.
If you know how to use a grease gun, they can be used around the house as well, but they are more efficient when it comes to heavy-duty commercial work.
How do Pneumatic Grease Guns Work?
As it was already mentioned, pneumatic grease guns work by using compressed air. Along with other components, this grease gun has two main parts – a grease cartridge holder and a pumping unit. This pumping unit has been connected to a high-pressure supply – sort of like you attach a compressor through a hose.
This kind of unit features a trigger mechanism that controls the grease gun while directing the airflow. The unit’s grease cartridge also features a spring mechanism – which will push the grease towards the pumping chamber. Once you press the trigger, the compressor will push the lubricant into the chamber through its nozzle.
Pneumatic Grease Gun Buying Guide
When it comes to buying a pneumatic grease gun, there are certain aspects that you might want to keep in mind prior to making this purchase. Here are the factors that every buyer should be looking into.
As with any tool that you may be using, you need to ensure that your grease gun is safe. Technically speaking, if the unit was manufactured in the EU, US, or Canada, then it means that it adheres to the strict safety standards.
However, if the product was manufactured somewhere else, then you may want to read the product’s fine print first. While most of these products will be required to obtain some safety certifications prior to being sold in the U.S., it never hurts making sure.
2. Pressure and Accuracy
A high-pressure pneumatic grease gun should be able to cover a larger surface much faster – which can be great if you have bigger spaces to cover. A low-pressure gun, on the other hand, should be able to provide more accuracy in a more specific area.
You must determine the kind of precision that you need when you are choosing your grease gun. Guns tend to have variable pressure, though – so, if you want more versatility, you may want to ensure that it is easily adjusted.
On average, a pneumatic grease gun should deliver an output pressure from 1200 to 6000 PSI – but this will depend on the model that you use. You may also want to check the input pressure as well – to see exactly what it can or cannot handle. You might be able to learn more about pressure input and output for air tools by reading through our homepage.
Pneumatic grease guns are by no means cheap. Since they are likely the most expensive of their kind, you don’t want to pay for one only to realize that it lasted as long as the warranty covered for it. You need to buy something that you know will last for at least a couple of years.
The average pneumatic grease gun should last for about a decade. However, depending on the materials that were used in its construction, it might last more or less.
The less plastic it uses, the better. However, you may want to read a few reviews first, as well. This should help give you an idea over its overall durability.
The accessories may differ depending on the unit that you are planning to use. However, the average pneumatic grease gun should come with a flex hose, an extension tube, and a nozzle. Some even come in their own portable case, which allows you to easily carry it from one point to the other.
Make sure that you always check the hose length. If the company does not mention it, you should be the one to inquire about it. If the hose is not long enough, then you might not be able to reach into the places where you wish to grease.
5. Size and Weight
Considering that you will probably have to handle it around all day, carrying it from one place from another, the last thing you may want is for your pneumatic gun to be very bulky and heavy. If that happens, you might simply decide to apply the grease by hand instead of using the product to automatically apply it.
For this reason, you might want to look at the size and the weight of a certain pneumatic grease gun. You can go for a heavier one if you only plan on using it every now and again – but if you want to use it on a daily basis, then you might want to go for something slightly more lightweight.
Some grease guns are filled through a barrel, whereas others are filled through a cartridge – and then into the barrel. While it might not make too much of a difference (other than the loading process), you might still want to keep this in mind when you are buying a grease gun.
How to Load and Use a Pneumatic Grease Gun?
Grease guns are very convenient when you have to apply some viscous lubricant onto the moving parts of a vehicle, which is why they are a common occurrence in garages and workshops. Similar to other tools such as the pneumatic nail gun, these may be quite confusing and difficult to load.
Since the pneumatic grease gun comes unloaded, you will have to do all the loading yourself. If you are not completely sure how to do that, here is a step-by-step guide for you. Bear in mind that the process breaks down into two categories, depending on the kind of grease gun that you own: loading the reservoir, and loading the cartridge.
1. Loading the Reservoir
First things first, you will have to load the main reservoir of the grease gun. Here is how you should be able to do so.
1.1. Separate the barrel and the head
Before doing anything else, you might want to first separate the head of the grease gun from the barrel. If you can get access to the bulk grease of larger containers, then loading it will be much faster. Slowly unscrew the two parts to ensure that your grease gun does not get damaged in the process.
1.2. Add the grease
You might either pout the grease into the reservoir, or you may add the open end into a bulk barrel – letting it automatically fill as you pull on the plunger rod. You might buy bulk grease containers from pretty much any hardware store.
1.3. Remove the barrel
Once the reservoir has been filled, it is time for you to remove the barrel from the grease container. Rotate it so that it breaks free from any grease that might be clinging onto the barrel, and then use a rag to wipe any remaining grease from the outside of the reservoir.
1.4. Close the barrel
Now that the grease has been added, reattach the barrel to the head. As each grease gun is different, you might want to read the instructions first – but make sure that it is properly sealed.
2. Load the Cartridge
While the process for loading a cartridge of a pneumatic grease gun might not be that different, as they both have barrels, it still differs at certain points. Here is how you load a cartridge grease gun.
2.1. Remove the old cartridge
When loading a cartridge grease gun, you should first secure the piston rod, after which you remove the cartridge. Most grease guns will have you moving the piston rod slightly sideways, into the barrel slot so that it is unable to move forward.
On the other hand, some grease guns will have the retracted piston latching into a fully retracted position, its release tab being positioned on the barrel’s end so that the piston cannot move. Once the rod has been secured into place, you may pull out the empty cartridge and then discard it.
2.2. Insert the new grease cartridge
Now that the old cartridge has been pulled out, you may prepare the new grease cartridge and insert it. Bear in mind that you might want to clean the barrel first so that it is inserted smoothly.
Insert the cartridge end that originally had the plastic cap on. Push it in completely so that the seals of the cartridge line up nicely with the barrel end. Remove the seal from the cartridge’s exposed end and then discard it.
2.3. Reattach the barrel to the grease gun end
Now that the cartridge has been inserted, it is time for you to reattach the barrel of the grease gun to the head. Screw it part-way – but not fully. Once you have done that, bring back the piston rod from its retracted position and push it back in the barrel while pumping the nozzle’s handle.
This will help disperse the air through the grease gun and get it going. Once that is done with and you see the grease coming through the head’s nozzle, stop pumping and screw the head and the barrel completely.
You can also see these both grease gun loading methods with pictures here.
How to Maintain a Pneumatic Grease Gun
If you want to avoid common grease gun problems and want it to work properly for a prolonged amount of time, you might want to follow through with a few maintenance tips. These tips are not only for the safety of your unit but for your safety as well.
- Read the manual carefully. Since every grease gun is different, you might have to proceed differently with its use and loading.
- Lubricate the insides of the cartridge regularly. This way, the plunger will fit in much better with the cartridge.
- Avoid mixing new grease with older grease – and make sure that you only use the lubricants that the brand recommends. Otherwise, you might end up only damaging the unit in the long run.
- Wear gloves, as this will put you out of direct contact with the grease.
- Check whether the grease is the kind that is flammable or not. If it is, then you might want to avoid flame while you are working.
- While the head needs to be fixed to the canister, refrain from fitting it too tightly. This might lead to excessive pressure buildup, which may affect the proper functioning of your pneumatic grease gun.
Once you have followed through with these tips, your grease gun should be able to function properly.
Pneumatic Grease Gun Accessories
There are several accessories, aside from the hose and the other essentials that might prove useful when it comes to handling a pneumatic grease gun. Here is what you might want to consider investing in.
1. Grease Gun Meter
When you are greasing a bearing or any kind of fitting, you might want to know exactly how much grease you are applying. If you use too little, you might end up shortening the life of that particular bearing. The same thing applies when you are using too much – and in this case, you’ll be wasting precious grease as well.
For this reason, you might want to invest in a grease gun meter, as it will measure the exact amount of lubricant that has been dispensed and then display it on the unit’s digital screen. With that in mind, you may easily make sure that you are only using the amount of grease that has been recommended by the manufacturer.
2. Needle Grease Injectors
Not every grease gun will have an accessory that allows you to reach into very narrow areas, universal joints, or sealed bearings. This is why it is very convenient to have some needle grease injector in your toolbox.
Most of these injector needles will feature standard grease fitting so that they may be used on most hand-operated grease guns. Moreover, they generally feature a protective plastic sleeve as well, for protective purposes.
3. Plastic Dust Caps
It’s no secret that debris and dust can greatly affect a grease gun’s contact resistance – in which case, you will need a cap that will protect it from corrosion and all kinds of debris. Depending on the set that you are buying, the dust caps may or may not be included in the kit.
If they’re not, you should know that they may be purchased separately as well – and in different colors, depending on your preferences and on the color of your actual pneumatic grease gun.
4. Grease Couplers
When it comes to couplers, there are various types you can use depending on their purpose. The most standard coupler available is the hydraulic one – which is also the most applicable model. You may also go for a three-jaw swivel model, as it provides a variety of locking positions.
Depending on the package, you might also come across some angled couplers or those that can be used for tighter, difficult to access places. The more couplers it has, the more expensive it might be – but in the end, it might offer you more versatility and better freedom of movement.
5. Grease Gun Case
As surprising as it may seem, not every grease gun comes with its own case. It might be simply sold in a box – and once you pull it out of the box, it is meant to go in your existent toolbox or any other place you may have designed for it. However, to improve its portability, there are grease guns that have their own case – which you may use for storage and/or transportation.
All of these accessories can accompany your pneumatic grease gun – or you may have to purchase them separately. Think whether you actually need these pieces or not, so that you do not end up wasting money needlessly on a particular product.
FAQ about Grease Guns
1. Do I Need to Use a Special Lubricant for My Grease Gun?
Not necessarily. Granted, each brand will recommend that you use a special or particular kind of lubricant – but in most cases, as long as it is of higher quality, you may use pretty much any kind of lubricant. However, to protect your unit, you might want to look into the possibility of purchasing grease made for pneumatic grease guns.
Bear in mind that two different types of greases should not mix. Many people put in new grease over the “leftovers,” and it ends up not mixing properly – damaging your grease gun in the long run. This is why you should make sure that you clean and wipe the container properly before adding a new lubricant.
2. How Do I Know I Over-Greased a Part? What about Under-Greasing?
Neither over-greasing nor under-greasing is good for your motor windings and seals, which is why you may want to ensure that you use the right amounts. Too much grease might jam your assets and damage your seals, whereas assets that were under-greased have the overall tendency to fail. You will certainly know when either of these circumstances happens.
3. The Canister Keeps Coming Away from the Head of the Grease Gun. What Do I Do?
There are generally two possible causes for this. First, this might happen because there is too much grease in the head, which usually results in a cross-treading. In this regard, you may want to wipe off the excessive grease.
The second cause might be that the head thread is too fine. In this case, there’s nothing much that you can do except for being careful when you screw the canister in the head. If the thread became too fine due to wear and tear, then you might also consider having that particular piece replaced.
The performance of your grease gun should never be underestimated, particularly if you tend to use it on a daily basis. If you work in a garage or at a workshop that has you greasing vehicles constantly, you should look into the best pneumatic grease gun to help you get the job done.
Hopefully, our pneumatic grease gun reviews turned out to be useful to you. These have all been set in different price categories – but regardless, they all provide great value through their features.
