One of the advantages of pneumatic tools in general as opposed to cordless ones in general is that they are much lighter.

How are Grease Guns Powered?

There are three main types of grease guns depending on how they are powered. These three types are manual, electric, and pneumatic. Depending on your application, the best grease gun for you may be any of them.

Manual Grease Guns:

Manual or handheld grease guns are operated using your hands. The grease is unloaded using the power of your hands. There are two types of handheld models: pistol grip and lever-action. Pistol grip models are operated with one hand and lever-action models have to be operated with two hands.

Electric Grease Guns:

Electric grease guns provide the most amount of versatility out of all the different types and they can provide the highest amount of pressure. There are two different types of electric models: corded and cordless. Nowadays, the most popular type of electric grease gun on the market is the cordless variety. The problem with cordless models is that they are heavier than every other type of grease gun but they are more portable and mobile.

Pneumatic Grease Guns:

Pneumatic models are the most heavy-duty type of grease guns. They can be used continuously for a long time and they are lightweight. If you get a pneumatic model, you will need to get yourself an air compressor. You need to check the requirements of your grease gun to get the right air compressor for your grease gun.

Maximum Pressure and Flow Rate

Different types of jobs require different amounts of pressure for different jobs. Heavy-duty equipment can not be lubricated properly with low pressure and if you use high pressure on components that are lubricated using lower pressure you can damage them.

The flow rate of a grease gun is the speed at which the grease is dispensed. A higher flow rate can save you a lot of time and make the task easier and thus save you a lot of energy as well. It’s better to get a grease that has a high maximum flow rate but still allows you to control the flow rate when you need to do more precise tasks.

Capacity

The capacity of your grease gun is important. A higher capacity means that the gun doesn’t need to be refilled as frequently. Most grease guns have capacities in the range of 13 to 16 ounces but some models offer even more capacity for high-volume applications.

Loading Method

There are three ways to load grease guns: suction, bulking, and cartridges.

  • With the suction method, the grease gun is loaded with grease in exactly the opposite way that it is used. In this method, you put the grease gun in the grease bucket and pull the plunger rod to fill the grease gun barrel.
  • In the bulking method, the barrel of the grease gun is filled by using a spoon. This method is relatively more time-consuming.
  • Using a cartridge is the easiest way to load grease guns. Whenever you need to load the grease gun, you just change the cartridge.

Attachments

Even if you have the best grease gun in terms of power and max pressure, you still need attachments like flex hoses to use your tool. You need to make sure that your tool comes with a long enough flex hose and the right type of coupler for your applications.

What about other qualities?

Other factors are extremely important when buying a grease gun. These qualities are durability, versatility, ease of use, and affordability.

  • Durability: This is one of the most important factors to consider for finding the best grease gun. These tools are used in rugged environments that can cause damage and corrosion to the body of the tool. Therefore, it is important to get a tool with a high build quality.
  • Versatility (Flexibility): Different equipment requires different flow rates and pressure. It’s essential to have a tool that can give you a different flow rate and pressure for different applications.
  • Ease-of-Use: One of the most important factors to consider for getting a grease gun is how easy it is to use the tool. This gets even more important in the case of handheld ones. Whenever you need to lubricate for a long duration, your hands could get fatigued if you do not have a grease gun that is not ergonomic and easy to use.
  • Affordability: The grease gun market is a diverse one. If you don’t have the budget for the most high-end models, you can still find products that can compete with the top brands in terms of quality at a significantly lower price point.
