Buyer’s Guide: Types of Grease Guns

Grease guns can be small or large and are sold in various formats and configurations. The following are a few types of grease guns that can be found on the market:

Lever Grease Gun

They are also known as manual grease guns. The lever handle gun is probably the most common design and the most popular style grease gun 10-20 or more years ago. These guns use a simple trigger mechanism to operate. The user can control the flow rate of the lubricant by managing his/her physical squeezing force.

They are rather simple and don’t have to be connected to any external device. The problem is you need three hands to use this if you don’t have a rigid tube. And with a rigid tube, you can’t always get in where you need to get to greases fitting.

If you got a locking coupler it makes the lever handle grease gun pretty ideal. You can reach up to different zerk fittings that might normally be out of reach of a rigid tube.

Hand Pump Grease Guns

These grease guns have a pressurized hand pump or piston. This hand pump is primed before use to build up pressure. There is a trigger mechanism in place which then releases the pressure and forces the lubricant to flow out through the fitting. This is why they are even marketed as pistol grip grease guns. 

Pneumatic Grease Guns

These guns find greater use in commercial and industrial applications. These air-powered models use an external air compressor to force the lubricant out; that pressure is provided to the tool in a mechanized way, which is why they are also called automatic models. These models are quicker and easy to use as compared to the above two.

Battery Powered Grease Guns

The basic lubricant oozing mechanism of these types of guns is the same as the above-mentioned guns. The only difference is that they come with batteries that provide power to the gun to build up the required pressure for forcing out the lubricant. That’s a great option if you don’t mind spending a little extra money and you have a lot of greases to do or if you just want something easy and clean to grease with.

How to Choose the Best Grease Gun

To buy the best grease gun on the market, you must keep in mind the important aspects that make it stand out. You have to keep the following factors in mind while selecting the best device for yourself:

Durability

You must consider the durability of the device. If it cannot stand the rigor of the job, then you should probably look elsewhere. Avoid a plastic build. Plastic grease guns will not be able to handle falls. A grease gun should be able to handle scratches and bumps. 

Ease of Use

These devices must be user-friendly, especially if you have never used one before. Avoid grease guns with difficult assembly. The gun should be simple to use. A gun with multiple features may sound tempting but that will make it complicated to use. Ease of use saves time and unnecessary frustration.

Amount of Lubricant

Determine the amount of lubricant you usually need to use for your lubrication jobs. Do you need the grease gun for your DYI projects or is it for your automotive repair shop? Defining the purpose of the grease gun will let you know whether you need a high-end, high-volume gun or just a portable small gun such as an Astro Pneumatic grease gun. 

Max Pressure and Strokes per Ounce

Manufacturers often mention the features of the gun in the product description – they vary from gun to gun. A more powerful and expensive grease gun will have more PSI rating and strokes per ounce. If you don’t understand these things and buy a gun that is not suitable for the job, then you might end up under or over lubricating your machine.

Points to Be Lubricated 

Identify the unusual areas that you need to grease. Some areas are much easier to reach with a certain type of grease gun. By identifying the lubrication points, you’ll also find out what type of gun you need. You may need a rigid or flexible extension depending upon your purpose. 

Fittings and Attachments

The type of grease gun you need can also vary with the type of fitting you may use. Different guns work best with some fittings. Some fittings have a ball check at the head, which prevents dirt from reaching the bearing. 

Loading Manner

While reviewing the device you want to buy, also check its loading manner. Different guns use different manners of grease loading. It may be by bulk, suction fill, or cartridge. Choose whatever you find the most convenient and easy.

Troubleshooting: Removing Air Pockets

Sometimes when you’re using the pistol grip if this doesn’t bleed out the air. You can loosen the barrel. Give it a few pumps and it should prime taking their backup and once she has primed you’re good to go stand. It’s time you change your tube grease. It should not give you any more problems.

FAQs

How do grease guns work?

A grease gun is called a gun because of its shape and basic mechanism. Manual grease guns force the lubricant out of the gun. Triggers can also force the grease from the barrel to the hose. The barrel is the area where the grease is stored. This oil is initially supplied to the barrel from the cartridge.
Some grease guns have paths for the grease to travel to a fixed or flexible tube. Guns have a part called the filler nipple; this is where the fluid is instilled from the pump. When the grease enters the head of the pump, the air escapes it. Springs provide pressure for the plunger. The follower rod helps the plunger as it puts the necessary pressure on the tube.

How do I change the grease gun cartridge?

Twist the body of your grease gun to separate the head of the cartridge and gun. Remove the head. Remove the string in the back of the grease gun, this will help in popping out the cartridge. Use paper to remove the cartridge.

What are grease guns used for?

Grease guns lubricate the joints and bearings of your machine; this reduces friction and increases the life of the machine. Greasing is important for the proper maintenance of mechanical equipment. Grease guns provide an exact and efficient application of the lubricant fluid. Grease guns have a variety of applications in various industries and DIY settings, but the following are its more common uses:
*Agricultural vehicles and machines
*Automobile maintenance
*Factory, plant, and processing systems
*Lawnmowers and chainsaw etc.

How do I store grease guns?

Store the cartridge tubes upright. Depressurize the gun if you are leaving the cartridges in it. Wipe it clean and place it horizontally in a cool and dry place; this will prevent leaking.

What are the signs of under-greasing?
