Grease gun buying guide
Basic features you need to consider
For any machine lubrication to be effective, there must be a thorough grease application to all tight areas and hidden corners. Regardless, you can reach all corners of your machine with the aid of the flexible hose at the very front of the gun.
The length of hoses varies from grease gun to grease gun. While some may be as long as 48 inches, some are just 18 inches in length. If the hose length is short, you may not be able to apply grease in some very tight spaces. But with long hoses, easy lubrication of difficult machine parts is a sure bet. All in all, the longer the hose, the better.
Besides, if the hose is rigid, you may find it difficult to adjust and control the gun properly when applying grease to some hidden parts of the machine. So, go for the flexible.
Pressure rating (PSI)
The power of a grease gun to push out a large amount of grease lies in its pressure rating. Before making a purchase, you should check the gun’s pressure rating to be sure it has enough power. As you’d probably expect, the higher the rating, the easier it is to push out grease from the gun.
Types of grease guns
Manual grease guns
There are two types of manual grease guns: pistol grip and lever grip that use no other power source other than manual labor. Manual grease guns are the most popular and economical type, mostly found in home garages.
Of all grease gun types, hand levers are the most common. They supply as much as 1.28 grams of grease on a single pump. If you are working on machine parts or grease fittings where precision is not so critical, you’ll find some of the best hand pump grease guns handy.
- Lever grip grease gun:
Recommended hose length: 20″
Recommended pressure rating: 10,000 PSI
- Pistol grip grease gun:
Recommended hose length: 18″
Recommended pressure rating: 7,000 PSI
Battery-powered grease guns
Battery-powered grease guns are cordless ones, and they deliver both power and convenience in a small, lightweight package. Look no further for greasing tools that deliver the highest amounts of pressure.
These tools have variable rates of grease flow, and they can be easily adjusted to control the quantity of grease released on every flow. Best suited for heavy machinery, battery-powered grease guns are also perfect for precision grease applications.
- Recommended hose length: 42″ or 48″
- Recommended pressure rating: 10,000 PSI
- Recommended battery:
Voltage (V): Battery voltages vary from grease gun to grease gun, and they are usually of three types: 12V/18V/20V. When the voltage is higher, the power is higher. However, the weight is heavier, and of course, the price is more expensive. But in general, 18V and 20V are the most commonly used.
Capacity (Ah): The capacity of the battery decides how long the gun lasts. It also determines how powerful the tools are. Higher capacity batteries have more cells (with parallel connection), which will deliver much more current (amps).
For 18V: get a 4.0Ah battery
For 20V: get a 5.0Ah battery
Brand: It is most advisable you buy a battery with the same brand as the grease gun.
Pneumatic grease guns
For a grease gun to use air pressure, it can build up to 6,000 PSI. Awesome, right? But that’s not all; such grease guns can also be fine-tuned for precision.
Some models of pneumatic greasing tools allow you to adjust the quantity of grease released on every stroke, while some are set to deliver just a fixed amount. Regardless, you can use it all for more specific maintenance jobs that do not require a very high PSI.
- Recommended hose length: 30″
- Recommended pressure rating: 6,000PSI
Mini grease guns
As the name implies, the mini grease gun is the type of lubricating tool you can use for mini projects. Given its small size, it is mostly used in homes and private business places; and it is an essential tool for tweaking equipment or machines.
- Recommended hose length: 12″
- Recommended pressure rating: 3,000PSI
American-made grease guns
There are several greasing tools made in America, from Alemite to Milton, down to SAE products heavy duty lever action grease guns. With such tools, smooth lubrication is made a no-brainer. You can easily lubricate your equipment yourself without requiring too much effort.
- Recommended hose length: 18″
- Recommended pressure rating: 6,000PSI
Electric grease guns
Electric grease guns work just like the battery-powered ones, but they are not exactly the same. They must be plugged into a power source. In electric guns, the pressure is also driven by an electric motor, and the motor drives pressure at a very high level. However, it is usually less-handy and may require a longer hose.
- Recommended hose length: 30″
- Recommended pressure rating: 7,000PSI
Keep in mind that this type of corded electric grease gun is not popular anymore because it is not portable. You may want to consider buying a battery-powered gun instead.
Top grease gun brands
There are many grease gun brands out there, but only a few can be classified as ‘best.’ The following brands have been found to be outstanding. So, before you ask, “what is the best grease gun to buy,” let’s check out the best brands available.

Grease gun pricing
This price point gives you just a few basic grease gun options to select from. The majority of the options available here are pistol grip, lever action, or mini grease guns, and they come with nozzles that can either be flexible or straight. Of course, the qualities of grease guns under $20 vary greatly, but you can get a perfect tool to keep your machines running smoothly.
Keep in mind that not all companies making grease guns can be trusted—some brands sell products that are way too low in quality. So, if you are going for something quite cheap, you should ensure proper cautions and confirm that the company is real.
Here’s some sort of middle-range pricing, and it consists of grease guns from $20 up to $70. You will find quite several quality options that are good and highly efficient in this range. Though many will be pistol grip and lever grip grease guns, there are still a couple of air-operated grease guns in the category.
Grease guns that cost more than $70 are mostly battery-operated and electric. They are the best options for industrial purposes, and they deliver the highest amount of pressure per pump.
Under this range, you will also find products that work perfectly for automotive applications. However, they are a better plunge for professional mechanics—the home mechanics do not really need them.
All over the world, grease guns are in different sizes and shapes. Whether you want them big and hulking or prefer yours to be small and portable, there’s one for you.
No one likes discomfort, so you may want to consider the gun’s convenience, among other things. Check out for grease guns that fit perfectly into your hand and can be used easily without stress.
Yes, abuse is inevitable when the purpose of a thing is not known. You’ve probably got a brand or two you admire the most, but before settling for any grease gun, you should ensure that it serves the exact purpose you need it for.
If you are not oiling up your car undersides, you might be looking to grease components on a chainsaw or lawnmower. And if none of these two options falls within the scope of what you need exactly, you’d probably be requiring a grease gun that’s truly multi-functional (one that can be used for quite a number of purposes, such as lever action grease guns). Grease guns are of different types, and each has its own particular use.
Your grease gun might not deliver properly if the length of the nozzle tube is quite too short. To grease your machinery in the most effective way possible, you need a more extended, flexible nozzle.
Flexible nozzles are best for smooth greasing, and they help to make your work easier. You can find them in an array of lengths and choose one that suits your particular needs.
The operation of a grease gun can only be as smooth as its quality. If you are particular about running a hassle-free operation, you should consider your tool’s quality.
With high-quality greasing tools, your efficiency increases, and you eliminate stress that comes with working with a stiff machine. That’s not all; they dispense grease precisely and evenly. They also get rid of air pockets via a bleeder valve. For effective results with your grease guns, endeavor to use the best lubricant for guns.
The best grease guns on the market today are made with metal, so if you are looking for something that will stand the test of time and serve you till hell freezes over, you know what to select. The low-quality options are ones that are mostly fashioned with some plastic components too. Unlike the purely metallic guns, they are likely to break and wear out with frequent use.
Before you jump on a grease gun and cough up hundreds of dollars to have it in your arsenal, be sure it poses no risk whatsoever to your well-being. In some extremely rare cases, a grease gun might not be safe for use in particular regards. So, you should know which tool is best for what purpose and use such accordingly.

1. Which is better, Milwaukee or Dewalt grease gun?
Both producers make some of the best cordless grease guns. They also offer a similar PSI pressure. So, the best grease gun depends on what you are looking out for. The DEWALT grease gun is perfect for big appliances and machines. However, its battery life is quite limited.
However, Milwaukee grease guns offer a lock feature and easy priming. Yet, it is relatively more expensive. Thus, your choice of either should be based on the function you’d like your grease gun to perform.
2. Should I oil the inside of a gun barrel?
Producers make the inside of gun barrels from steel. It’s possible for the steel to rust and destroy the grease gun. So, it’s best to oil your oil barrel to keep it lubricated and free from rust.
3. How much pressure can a grease gun produce?
The pressure from a grease gun depends on type and age. First, the type of grease gun determines how much pressure it produces. The lowest tier of grease guns produces as little as 1,000 PSI. On the flip side, higher-end grease guns can let out pressure of up to 15,000 PSI.
Moreover, the pressure of a grease gun reduces over the course of use. As a result, a 2-year-old grease gun’s pressure will be significantly lower than a brand-new gun of the same type.
4. How often should I clean my gun if I don’t use it?
It is best to clean your grease gun twice every month if you don’t use it. However, you should try to clean and learn how to maintain your grease gun before and after each use. If your gun stays too dirty for too long or are not used properly, you may have to throw it away.
Grease guns provide an excellent, stress-free method to lubricate your gadgets. Fortunately, there’s a wide range of the best grease guns for you to choose from. Yet, you must consider all relevant factors before deciding what grease gun to buy.
For household uses, manual and smaller size grease guns are perfect for you. However, industrial uses may require powered-battery, electric and pneumatic guns. Either way, ensure you don’t compromise safety and buy within your budget. Thankfully, this best grease guns review 2021 helps you make the right choices.
