When you plan to use your grease gun, knowing all about its anatomy will help you look after, care for, and even handle this vital piece of equipment. Not only will this help you prepare for use, but a proper understanding of your grease gun will help you increase its lifespan, ensuring you are equipped long into the future.

Part of understanding grease gun use is to familiarize yourself with grease gun anatomy.

Let’s cover some frequently asked questions about grease guns.

1). How Do Grease Guns Work?

Grease gun operations differ depending on the type of device you’ve chosen to use. Typically, grease guns use a range of pressure outputs to remove clogs from machinery and vehicles such as tractors or other farming equipment.

2). What Are Grease Guns Used For?

Grease guns are used to ensure your mechanics are running smoothly by cutting through clogged grease.

3). What Are The Three Types of Grease Guns?

There are three types of devices that commonly feature in our kits.


Manual grease guns transmit from a hand pump into an aperture. They are operable by either one or two hands, and are a perfect option for low-use, low maintenance grease removal.


Pneumatic solutions use compressed air directed inside the grease gun hose.


A battery-powered gun works like the pneumatic, but has no cord – allowing you to work flexibly in wide spaces with no electrical outlets, or out on a job.

4). How Can I Improve My Grease Gun? 

There are some key components to upgrading a grease gun that allow you greater use. These parts include:

  1. Grease gun couplers
  2. Grease gun connectors
    3. Grease gun adaptors

Most grease guns typically already have a hydraulic coupler. However, other adaptors are available in several configurations (including needle-end solutions for precise spotting, 90-degree devices for confined spaces, and three-jaw couplers for numerous applications).

5). What Are Some Upgrades For My Grease Gun? 


There are a few options to upgrading your grease gun, including purchasing extra additions. For example, you might decide to retrofit your gun with a meter to maximize lubrication. You could also consider upgrading with sonic and ultrasonic options.

Hoses and Tubes

A grease gun tube can be an adaptable hose or fixed tube. You’d want a hose for difficult reaches, but a fixed tube is best for level-style gunning.


Fittings manage points of the grease connector attachments.
We recommend using flush fittings for tight spaces, allowing you to prevent high pressures that can damage seals.

6). What Do I Need To Know About Grease Guns?  

Take Care of Your Grease Gun

Unnecessary pressure can cause serious damage. Guns can deliver up to 15,000 psi and it’s important to know the right amount of pressure to apply to protect your belongings, your gun, and yourself. 

Have Caution When Applying Grease

Not knowing how to precisely measure greasing can lead to damaged seals, fluid friction, and unwanted consumption. 

Proceeding with caution can help you protect your machinery and avoid making mistakes. If you find yourself in any doubt about the capability of your grease gun in fixing a problem, be sure to consult one of our experts.
