Grease Gun Buying Guide, Tips

Best grease gun - brand new

This comprehensive buying guide provides the knowledge you need to find the best grease gun for your various lube jobs.

What Is A Grease Gun?

A grease gun is a handy lubrication tool used to apply grease or some other type of lubricant to various mechanical or moving parts. It’s designed to dispense lubricant under pressure, forcing it into specific areas of a rotary bearing that would otherwise be difficult without disassembling the surrounding components.

While grease guns are widely used by mechanics and engineers and normally associated with machinery, they are also used by hobbyists and everyday people for pretty much anything that has a moving part, such as toy models, oven and refrigerator components, door hinges, etc.

How Do Grease Guns Work?

Like a real gun, grease guns normally have a grip, a hose or fixed tube serving as a muzzle, a lever or some other type of trigger, and a barrel or chamber that is loaded with either grease or a grease cartridge. 

Pulling the trigger causes the grease to be released from the chamber, passing through the hose or tube directly to the precision point.

What Is A Grease Gun Nipple?

Grease fittings or nipples are not a part of the grease gun like many laymen believe but rather a fitting located on the body of the vehicle or equipment being lubricated.

They feature a small aperture in the top, with a slim channel behind their opening that runs directly to the area (e.g. voids of a bearing) that needs to be greased. 

A grease gun’s nozzle fits snugly over the nipple so that when the lubricant is pumped, it flows through the hole in the fitting, into the channel, and directly to the part of the equipment that needs lubrication.

Although not always necessary, using a grease gun together with a grease nipple makes lubricating hard-to-reach places easier, quicker, and more precise.

5 Reasons Why You Need A Grease Gun

There are several compelling reasons why you should use a grease gun for your various lube jobs, be they in your garage or around the house.

1. Prevents waste: Trying to lubricate machine parts by hand oftentimes causes more grease to be used than necessary. A grease gun helps prevent waste by delivering a more accurate amount of grease every time.

2. Improves accuracy: Whereas other methods disperse grease by spraying a shot over the target areaa grease gun allows you to more accurately hit and saturate the precise points where the grease is needed.

3. Saves time: The last thing anyone with a busy schedule wants is to waste what little time he or she has greasing something up. A grease gun lets you get the job done quickly but effectively, giving you more time to spend on more important tasks.

4. Saves money: Since using a grease gun cuts down on wasted grease, you effectively save money in the long run.

5. Extend Longevity. Under-greasing or over-greasing can adversely affect the longevity of the parts or components being worked on. With a grease gun, you are better able to achieve the optimal level of saturation needed to maintain or improve the durability of the parts.

The 4 Types of Grease Guns

There are four main types of grease guns:  Lever, pistol grip, pneumatic, and battery-powered.

1. Manual (Lever) 

With this type of grease gun, the user pulls a lever to build back-pressure that forces the grease out.

Manual grease guns with a lever are the most common type of grease gun. They can build a decent amount of pressure and are best suited for jobs that don’t require the utmost precision.

2. Manual (Pistol Grip) 

Lacking a lever or trigger, these grease guns require the user to push on the butt of the grease gun, which slides a piston through the body of the tool to pump grease out of the aperture.

3. Air-powered (pneumatic)

This type of grease gun uses a hose to direct compressed air to the gun, with the air pressure forcing the grease through the aperture. 

Air-powered, or pneumatic, grease guns generally offer more power than their manual counterparts and can be calibrated for precision. This makes them a great option for large commercial projects, as well as tasks requiring precise grease application.

4. Battery-powered

This is a low-voltage, battery-powered electric grease gun that works in much the same way as a pneumatic grease gun but with the added benefit of being cordless.

Not only are battery-powered grease guns the most convenient to use, but they typically also provide very high PSI and easy adjustability for controlling the amount of grease dispensed per stroke. Like pneumatic grease guns, they are great for heavy-duty, high-precision applications.

Top Grease Gun Brands

There are many grease gun brands to choose from. However, the following companies and brands often dominate the conversation due to their strong heritage and continued excellence in delivering top-rated products, at least in North America.


Originally founded in 1923, DeWalt is an American global brand that manufactures power and hand tools for the manufacturing, construction, and woodworking industries. The DeWalt  20V Cordless Grease Gun is one of their best-selling products.

Lincoln Industrial

Lincoln Industrial Corporation is a renowned manufacturer of lubrication equipment and industrial pumping systems. Founded in 1910, the company has been a leader in innovation for modern lubrication practices in automotive maintenance. The Lincoln Industrial Air Operated Grease Gun is highly-regarded by mechanics, engineers, and the like.


Credited with introducing the first portable, one-handed quarter-inch capacity drill, Milwaukee Electric Tool Corporation is an American manufacturer renowned for making high-quality power tools. The Milwaukee M18 Grease Gun is one of the highest-rated grease guns on the market.

How To Choose The Best Grease Gun

Finding the best possible grease gun for your projects requires considering five essential features of grease guns:

1. Grease PSI (Pounds Per Square Inch)

PSI stands for pounds of force per square inch and is a unit of measurement used to determine pressure level.

Most grease guns are capable of sustaining a PSI of 2,000 to 15,000. 

Generally speaking, the higher the grease PSI, the better the flow. However, too much pressure — anything above 500 PSI in some instances — can damage the bearing seals on some guns.

To avoid this from happening, don’t buy a grease gun until you check the specifications for its bearing seals or shields. Opting for a model that lets you adjust the pressure will make your life easier.

2. Grease Output

Like pressure intensity, knowing how much grease a grease gun puts out per stroke is crucial for preventing over and under greasing problems. 

Grease output varies from grease gun to grease gun, but it generally ranges from 0.5 grams to more than 3 grams. The best grease guns tend to feature a grease meter that allows the user to easily monitor the grease output and more effectively control it.

3. Safety And Durability

A grease gun should pose no risk of damage to the user and the object it’s being used on. It should adhere to established safety standards.

Moreover, the gun should be constructed with long-term use in mind. The use of high-quality metals and other materials is usually indicative of a solid and durable product that will last.

4. Grease Loading Method

You can load a grease gun either by filling the barrel directly with grease or by inserting a cartridge. Some models give you both options.

Cartridge-loading is typically quicker and cleaner than suction-loading, hence why cartridge-loading grease guns are more expensive on average than reservoir-loading guns.

5. Fixed Tube vs. Flexible Hose

Choosing between a flexible hose or a fixed tube will depend on the type of grease gun and the accessibility of the area that needs lubricating. 

For example, a flexible tube would be best-suited for hard-to-reach areas. However, they are not as sturdy as fixed tubes and, therefore, break more easily.

Other Considerations

Here are six other factors to consider when buying a grease gun. 

  • Intended purpose: What will the grease gun mostly be used for? Will it be used for small or large, heavy-duty applications? Do you need something simple or multi-functional? Knowing this is important because not all types of grease guns are ideal for every type of application.
  • Nozzle type: Grease guns tend to come equipped with either a short, straight nozzle or a flexible metal one. For hard-to-reach places, you’d want a flexible nozzle. 
  • Tube length: In addition to the type of nozzle, you need to determine the right length of the nozzle tube for your particular needs. The length helps ensure the proper delivery of the grease to the targeted site.
  • Barrel size: A bigger barrel size will favor tasks requiring a high volume of grease to be deposited in a short amount of time, while a smaller barrel works well for small specialty applications.
  • Design, quality: You want an effective, high-quality grease gun that’s smooth to operate. It should be easy-to-use, dispense grease evenly and precisely, and efficiently eliminate air pockets.
  • Ergonomics: A grease gun should feel comfortable in your hands. Models featuring a cushioned grip and thumb-slot divot are easier and more comfortable to hold onto.

Using And Maintaining A Grease Gun

Man using best grease gun on a car

This section covers the best practices for loading, using, and maintaining a grease gun effectively.

How To Load A Grease Gun

A grease gun in one of two ways: 1) Fill the barrel directly with grease, or 2) Insert a cartridge. 

Steps For Bulk Loading Grease Gun From A Container

Filling a grease gun barrel directly with grease is a fairly straightforward process:

Step 1. Open the up the grease gun barrel

Step 2. Place the end of the barrel into the container of grease

Step 3. Pull the plunger to fill the barrel with grease

Step 4. Clean the rim of the barrel, and put the lid back on

Step 5. Push the plunger back down to pressurize the grease 

Steps For Cartridge Loading A Grease Gun

Step 1. Open the barrel by unscrewing the gun head

Step 2. Pull back the rod handle and lock it into place

Step 3. Insert the grease cartridge into the barrel and pop open the lid

Step 4. Reattach the gun head back to the barrel

Step 5. Push the rod handle back down to compress the grease

Step 6. Test to see if grease comes out

How To Use A Grease Gun

Each type of grease gun works differently. With grip guns, you hold the two grip points in your hand and slowly squeeze to fire out the grease. The faster you squeeze, the more pressure you get.

Battery-powered and pneumatic (electric) grease guns are by far the easiest to use because they are powered electronically. All you have to do is simply push a trigger to get the grease flowing. 

Some electric guns have pressure variances that are usually controlled with a little knob on their side.

How To Maintain A Grease Gun

As with any other maintenance and repair tool, grease guns need to be maintained properly to work optimally. Here are some best practices for keeping your grease gun in the best possible shape:

  • Don’t mix two different types of lubricants. Only use the type of lubricant recommended for the parts and components you’re tasked with.
  • Always clean the grease gun and after using it and before/after loading it. Make sure to also clean the grease nipple fittings.
  • Regularly inspect grease fittings for damage; replace them if you notice any unusual defects.
  • Don’t overload the grease gun. Doing so can damage its seals.
  • Prevent contamination by lying the grease gun on clean surfaces and covering it when not in use.
  • To prevent grease from leaking out, store the grease gun in a horizontal position, ensuring that no pressure is placed on the trigger or lever. The grease nipples and fittings also need to be cleaned before the grease gun nozzle is attached.
  • Keep the grease gun away from fire. Among other potential hazards, the pressurized barrel can explode if too hot.

Grease Gun Accessories

Grease guns can be retrofitted with a variety of accessories that make them easier to use and allows them to customize for specific tasks. Couplers, grease fittings, meters, and plastic dust caps are the most common grease gun accessories. 

Grease Gun Couplers

The coupler (connector) serves as the connection point linking the hose or fixed tube attached to the head of the grease gun. They come in several variations, each best suited for specific applications.

  1. Standard hydraulic adapter. This coupler adapter provides a quick, leak-proof connection for greasing standard grease fittings. It’s the most commonly-used adapter type.
  2. 90-degree adapter. As the name suggests, this L-shaped adapter is best suited for grease fittings that can only be accessed from a 90-degree angle, especially those installed in tight spaces.
  3. Needle-end adapter.  These couplers are optimized for precision, featuring a very thin design that helps deliver precise amounts of grease for hard-to-reach places.
  4. Three-jaw swivel adapter. As the most versatile coupler, this design offers a variety of locking positions for different applications.

Grease Fittings (Nipples)

The grease nipple or fitting is the lubrication point on the machine or equipment where the grease gun’s nozzle is attached. There are four main types :

  1. Standard hydraulic fitting. This is the most common fitting type. They are designed to either angled or upright.
  2. Button head fitting. This is the grease fitting to get if you need to apply large volumes of grease.
  3. Flush-type fitting. These grease fittings have less protrusion than the other types, making them ideal for installations where standard protruding nipples cannot be used, such as those in tight spaces.
  4. Pressure-relief vent fitting. These fittings have a unique design that helps them prevent the build-up of excess pressure, which can damage the seals.

Grease Gun Meters

Knowing exactly how much lubricant you’re applying is important to effectively using a grease gun, seeing as under-greasing or over-greasing can shorten the life of the bearing element and result in costly breakdowns.

Unfortunately, not every grease gun gives you a way to monitor your usage level. Fortunately, the ones that don’t can be retrofitted with a grease gun meter, a device that displays the amount of lubricant dispensed on a digital screen.

Plastic Dust Caps

Dust and debris can damage machinery if they get into the lubricant. Not only can they interfere with the lubricant’s flow and ability to maintain a protective layer between the moving parts, but they can also scratch and dent metal surfaces.

Plastic dust caps can protect the gun and the grease fittings from corrosion and prevent the lubricant from becoming contaminated. You can even color-code them to avoid cross-contamination. 

Grease Gun FAQs And Answers

Question mark sign - Best grease gun

Want to learn more about grease guns? These frequently asked questions and the answers to them provide more insight into how they work, how to use them, and how you can find the right one for your lube jobs.

What Is The Best Grease Gun?

You are spoiled for choice when it comes to high-quality grease guns. DeWalt, Lincoln Industrial, Milwaukee, and Lumax, in particular, have earned a strong reputation for offering a wide selection of top-rate grease gun models.

What Grease Gun Is Best For Automotive Use?

The best type of grease gun for your car will depend on the type of car you have, how often you want (or need) to apply grease, and the areas the vehicle the grease will be applied.

For occasional use, a pneumatic or hand lever grease gun will get the job done in most cases. But for more frequent use, your life will be easier with a battery-powered one.

How Do I Load And Unload A Grease Gun?

How you load a grease gun will depend on whether you have a cartridge or a reservoir grease gun. With cartridge grease guns, you need to unscrew the gun head from the gun’s barrel, remove the old grease cartridge and insert the new one, and reattach the head.

Loading a grease gun via a reservoir or suction, on the other hand, requires removing the head, placing the barrel’s opening into a grease bucket or container, and pulling the gun’s plunger upwards to fill the barrel with grease.

How Often Should I Grease My Car or Truck?

Most modern cars have very few, if any, grease points that need to be periodically lubricated; however, hinges, latches, windshield wipers, and wheel hubs still need to be routinely lubed. 

Although the frequency will depend on the specs of your vehicle (check your car’s owners’ manual), it is generally recommended that you apply grease halfway between oil changes and then during the oil change.

For example, if your car needs an oil change every 10,000 miles (16,093 km), you may want to grease it after 5,000 miles (8,047 km) and then again at 10,000 miles.

What Are The Signs Of Under Or Over Greasing?

Friction wear is the most common sign of under-greasing, often causing machine parts to make weird sounds and overheat.

Common symptoms of over-greasing are collapsed seals, high operating temperatures, and motor windings. Too much grease can even cause electric motors to lose energy or fail outright.

How Much PSI Does A Grease Gun Produce?

It depends on the type and model of the grease gun. Many high-end grease guns produce anywhere from 7,000 PSI to 15,000 PSI, while lower-end models can deliver up to 2,000 PSI. 

Final Thoughts

There are so many grease gun models on the market that you’re basically spoiled for choice. For general household and car maintenance tasks, save money by getting one of the cheaper, manual options. For more professional jobs, we suggest a pneumatic or battery-powered gun. 

Pneumatic and battery-powered grease guns are expensive, but the precision and variable pressures they offer make them great for basically any job.

The DEWALT 20V MAX Cordless Grease Gun is our choice for the best grease gun due to its efficient grease delivery system and solid build quality. For something less sophisticated and more affordable, consider the Lumax LX-1152 Heavy Duty Pistol Grease Gun.
