What are the must have things to consider before buying the best air grease gun? 

There are various types of a grease gun for air tools which come with versatile features and specifications. Depending on the project type and frequency of use, certain types and features are suitable. So, how do you know which grease gun is the best one for you? You need to pay attention to some essential features to understand the quality and performance. Here I am discussing must-have features that would help you find the ideal pneumatic grease guns.

Type

There are different types of grease guns in the market, such as pistol grip grease guns, lever grease guns, pneumatic grease guns, and cordless grease guns. Each gun is designed with certain capabilities. So, you need to choose the right one depending on the project you work on.

Materials

The durability of a grease gun depends on the material used for manufacturing the gun. You will find grease guns with metal bodies; these are strong and can withstand pressure. So, choose a grease gun that is built with high-quality material.

Size and Weight

If you are looking for an air grease gun for project work, then the chances are that you will use it frequently. Sometimes you may need to carry it to different places. Hence, it's important to choose a portable and easy to handle air grease gun. So, choose a pneumatic grease pump that is lightweight and comes in a compact size.

Maximum Operating Pressure (PSI)

By PSI rating, you can understand the amount of grease the machine will release with one press. If you are lubricating any clogged fittings, then you will need high PSI because the higher the PSI, the better and faster to cover a large surface. Nevertheless, the low-pressure gun is more suitable for a small area to apply grease with precision. Usually, an average air grease gun delivers from 1200 PSI to 6000 PSI. So, choose the PSI rating that is just above the pressure you need for your project.

Nozzle

The nozzle of the grease gun impacts how smoothly the grease will deliver. You will find two types of the nozzle. One is straight and short, and the other one is a flexible metal nozzle. The length may vary depending on the grease gun. If you need a grease gun to reach a tight spot, then you should choose the flexible nozzle.

Grease reloading mechanism

The mechanism of reloading grease is an important feature to consider. The grease guns are available with diverse reloading mechanisms such as cartridge loading, suction loading, and bulk loading. Compared to the three loading systems, cartridge loading is easier, convenient, but a bit expensive.

Whereas in the suction loading mechanism, you need to refill the gun manually. And, in the bulk loading method, you need a bulk loading coupler, fitting, filler pimp, and bleeder valve. It is the easiest and affordable loading system for an air-powered grease pump.

Durability

The durability of an air tool grease gun depends on the material used in the making. Certainly, you don't want to spend a high price on a product that won't serve you long. Compared to metal grease guns, plastic guns are less durable. So, be careful about the material of the grease gun to ensure durability.

Safety Features

Grease guns are a tool that you need to use regularly. So, you need to make sure it comes with the required safety features. Usually, in Europe, Canada, and made in USA grease guns tend to follow the safety standard while manufacturing their product. If your grease gun is from somewhere else, then it's recommended to read the product details first.

How does an air grease gun work? 

Up until now, you already know the air grease gun works with compressed air. To be more specific, the gun comes with two parts. One is the grease cartridge holder, and the other one is the pumping unit. The pumping unit is connected to the compressor using a hose so that it can supply the grease.

The cartridge of the gun has a spring that forces the grease through the pumping chamber. There is a trigger that is attached to the gun to supply the grease at the targeted spot. You can easily control the gun and direct the airflow with the trigger. So, as you push the trigger, the compressor will force the grease to pass through the chamber, and the nozzle will deliver the lubricant.

Benefits of using Air Grease Gun 

Naturally, most users think an air grease gun is for lubricating vehicles and machinery. This is true. However, have you ever thought that there are other benefits you can enjoy from an air grease gun? Probably not!

Here I am going to highlight some of the extraordinary benefits that an air grease gun can offer.

Waste prevention

The most essential benefit you can enjoy with a grease gun is you can use grease, oil, and any kind of lubricants. It means one device is suitable for multiple types of lubricant, which is a cost-effective solution. Moreover, with an air grease gun, you can control the amount of grease you are going to apply.

Normally, while applying grease with a hand or any other tool not only wastes a lot of greases but also makes the job messier. But, an air grease gun will help you from overflowing the product and use only the necessary amount.

Time Saving 

Whether you are working on a DIY project or industrial purpose, lubricating several parts, vehicles, or machinery becomes a time-consuming job. Because people are used to greasing these items with their hands.

But, when you have a pneumatic grease gun, you can do the job in a few minutes. So, you don't have to waste a whole day lubricating one vehicle. Thus, it has become a popular tool for automobile shops, personal and commercial purposes.

Precise application

One of the main reasons for using an air grease gun is you can apply lubricant just at the right spot. Since the gun comes with a nozzle, you can easily apply grease in narrow spots to a large surface. You just need to press the trigger, and the nozzle will pass the lubricant. You can also control the flow and change the direction if needed. So, the chances of creating a mess while applying grease are very minimal.

Cost effective

As grease guns are an effective lubricating tool, you can apply grease with accuracy and the right saturation. Thus, it not only saves your time but also saves the product. Moreover, it also increases the lifespan and reduces the repairing cost of the components you are lubricating. Hence, in one way, it's saving the repairing cost of the items as well as prevents the overuse of the product.

How to load and use an air grease gun? 

Without a doubt, air grease guns are an essential tool for mechanical projects and workshops. Since there is a wide diversity in grease guns, it might be confusing for many users to understand how to load and use them. Also, the pneumatic grease guns need to load manually.

So, if you are a beginner and have no knowledge about how to load the gun, here is your chance to have a basic idea. Having said that, the mechanism might be different depending on the type of grease guns you use, but the step-by-step instruction will help you have a general idea.

How to load the reservoir? 

Step 1: Separating the barrel and the head

First, you need to separate the head and the barrel from the grease gun. You need to unscrew these two parts using a screwdriver. But, be cautious that you don't damage the parts during the process.

Step 2: Inserting the grease

Now, you can insert the grease into the reservoir or load the grease from the bulk barrier. Inserting the grease from a bulk container is very convenient because you just need to put the open end inside the barrel. Then, you will have to pull the plunger rod, and it will automatically fill in the grease.

Step 3: Removing the barrel

When the reservoir is filled, you need to remove the barrel from the container carefully. To do that, you just need to rotate the barrel so that it is separated from the dripping grease. Then, use a rag to wipe out the grease residue from the barrel as well as the reservoir.

Step 4: Closing the barrel

As the barrel is filled with grease, you need to reattach the head and the barrel. At this point, you need to ensure the parts are properly sealed. Otherwise, you may face overflowing grease during use which will create a mess.

How to load the cartridge? 

Step 1: Removing the old cartridge

To remove the old cartridge, you need to secure the piston rod first. Usually, you need to move the rod sideways inside the barrel. Thus, it will not be able to move forward. As you secure the rod, you can remove the old cartridge easily.

Step 2: Inserting the new grease cartridge

After removing the old cartridge, you need to insert a new one. But, before that, clean the barrel properly so that you can insert the new cartridge smoothly and quickly. Once the barrel is clean and tidy, you need to push the cartridge inside. The seal of the cartridge should be parallel with the end of the barrel. After the insertion is complete, remove the seal from the open end.

Step 3: Reattaching the barrel

Now the new cartridge is loaded. At this point, you need to reattach the barrel to the head of the gun. You need to unscrew the parts slightly. Then, reposition the piston rod that you secured sideways and push it back inside the barrel. If you can do it perfectly, you will notice the air is dispersed, and the grease is passing towards the nozzle head. Refrain from pumping the gun; rather, screw the barrel and head tightly.

How to use an air grease gun? 

Now you know how to load the reservoir and cartridge. It's time to learn how to use the grease gun. Using an air-powered or pneumatic grease gun is very easy. The gun uses compressed air, which adds pressure to the piston. The air pushes the lubricant out of the coupler and passes it in the grease fitting. Now, press the gun trigger at the required proportion and apply the grease to the spot you need.
