A grease gun is an essential piece of equipment for many professionals and homeowners who own a variety of power instruments. They aid in lubricating the parts for smooth operation by minimizing friction between them. This, in turn, helps keep the devices from wearing out too soon.
Even though many automakers claim that their vehicles’ ball joints, steering knuckles, and other components are “lubricated for life,” possessing a grease gun is still beneficial.
However, component failures do occur, and aftermarket replacements may or may not be sealed, necessitating lubrication.

How Grease Guns Work
A grease cannon is needed for older automobiles, farm and yard equipment, trailers, and even some power tools that require periodic lubrication. It pumps heavy lubricants into mechanical components for suspensions and driveline systems.
Greaseable components are outfitted with a unique nipple known as a “Zerk” fitting. The grease gun has a nozzle that securely couples with the Zerk fitting and forces grease into the fitting under pressure. Typically, pressure is delivered manually with a pistol grip or lever.
Some more complex grease guns are pneumatic, powered by an air compressor, or powered electrically by a rechargeable battery. Grease guns are loaded from a huge container or a handy cartridge.
Grease guns dispense grease to lubricate equipment parts. It prevents pieces from rubbing against each other and causing excessive friction.
Many spots can be extremely difficult to apply oil to; grease guns can help grease these tight areas quickly and with little effort. Grease guns come in a variety of styles, including battery-powered, air-powered, and basic manual grease guns.
How to Choose a Grease Gun
Choosing the best grease gun is dependent on a number of things. A good alternative usually spreads the grease correctly and rapidly, with no mess.
When there are so many different options, it can be difficult to choose the perfect grease gun. Hence, we hope this guide can assist you in selecting the appropriate grease gun model for your application.
What Exactly Is A Grease Gun?
A grease gun is a tool for lubricating mechanical joints and fittings. Machines with moving parts generate friction, which wears down and finally destroys critical components. To reduce wear, each location where metal rubs against metal should be greased with grease or oil.
Machine joints might be difficult to access in many circumstances. A grease gun often has a long, flexible hose and a unique coupler that allows it to apply grease directly where it is needed.
It is a tool that is typically seen in workshops and garages since automobiles and other heavy machinery require greasing as part of routine maintenance.
Grease Gun Types
Grease guns are classified into four types:
These require two hands to operate via a hand pump and deliver the most grease per stroke of any gun. For best use, they can be outfitted with a variety of accessories and adapters. Because of their simple construction, lever-action rifles are ideal for do-it-yourself projects.
These may be used with one hand and are perfect for tight spaces. They emit less grease per pump than other guns but have a more precise aim, making them excellent for automotive applications.
For more portability, these feature rechargeable Lithium-ion batteries. They are actuated by a trigger and deliver a small amount of grease per draw.
A steady stream of grease is delivered by an external air compressor. For high-volume applications, users typically pair this with bulk-loading equipment.
Important things to consider while choosing a grease gun
- Pressure Rating: Enough pressure should be present for proper grease dispersion from the grease gun. These weapons are offered in a range of pressures, from 3000 PSI to 10,000 PSI. A low-PSI cannon does not apply enough grease to large equipment, but a high-PSI gun may damage smaller equipment.
- Grease Loading Methods: Grease can be loaded in one of three ways: bulking, cartridge, or suction. The cartridge is the simplest and least expensive method of loading the grease. Suction is difficult to load, and bulking is a straightforward but time-consuming procedure.
- Hose Length: Applying oil in tight areas and small corners is challenging and necessitates the use of a flexible hose. As a result, most grease guns have an 18-inch flexible hose to appropriately apply or discharge grease on car or tool parts or components.
Some grease gun types even have a longer hose length of roughly 27 to 42 inches. The type of equipment that will be lubricated using these guns should be taken into consideration while determining the length of the hose.
Grease Gun Accessories and Fittings
Many grease guns come with a common hydraulic connection adapter, although there are various variations depending on the application. For example, 90-degree adapters are good for reaching around corners and bends, whereas needle-end adapters are ideal for reaching into narrow crevices.
Depending on the grease-fitting type, ease of position, and type of gun, grease guns have either a fixed or flexible (flex) hose. Guns with flexible hoses are better suited for hard-to-reach areas. Grease guns, on the other hand, are often operated with two hands and employ fixed hoses for superior aim.
A grease fitting, also known as a Zerk or Alemite fitting, is the lubrication point to which a grease connector is attached. For better application, the standard fitting can be upright or inclined. Button-head fittings are better for applying large amounts of grease, while flush-type fittings are best when space is restricted for protruding fittings.
A coupler is a handy grease gun attachment that makes attaching a Zerk fitting easier. The LockNLube coupler helps prevent leaking, saving time and money in the long run. The disadvantage of using a coupler is that it can be difficult to situate it in tough-to-reach spots that only a flexible hose can reach.
Which Grease Is Best For Grease Guns?
Your project will determine the optimum grease to use in your grease gun. There are three types of grease used for mechanical lubrication: all-purpose (AP), multi-purpose (MP), and extreme pressure (EP).
- AP grease is intended for general use and is suitable for squeaky doors and some ball joints.
- MP greases are more durable than AP grease, but they are also more expensive. These greases are suitable for use in automotive applications.
- EP grease is the most long-lasting form of grease. This grease is thick and tacky, and it may contain anti-wear compounds such as molybdenum (thus the name moly-grease).
