Grease Guns
Before diving into the process of how to lubricate a grease gun without a cartridge, let’s briefly understand how grease guns work.
A grease gun is a mechanical tool designed to deliver grease to various components of machinery or vehicles. The gun typically consists of a barrel, plunger, and nozzle. The grease is loaded into the barrel and expelled through the nozzle when the trigger or plunger is actuated.
Most grease guns are designed to be used with cartridges, which contain pre-packaged grease. However, there are situations where you might need to load grease manually.

How to Load a Grease Gun Without a Cartridge: Step-by-Step Guide
Now, let’s delve into the step-by-step process of how to load a grease gun without a cartridge:
Step 1: Prepare Your Grease Gun
Ensure your grease gun is clean and free from any old or hardened grease. Clean it thoroughly to prevent contamination of the new grease you’re about to load.
Step 2: Select the Right Grease
Choose the appropriate grease for your equipment or machinery. Check the manufacturer’s recommendations or consult equipment manuals for guidance on the correct type of grease to use.
Step 3: Fill a Container with Grease
Take your chosen grease and transfer it into a clean container. This container will act as your makeshift cartridge, allowing you to load the grease gun manually.
Step 4: Load the Grease Gun
Now, it’s time to load the grease gun:
- Remove the plunger from your grease gun.
- With the plunger removed, insert the open end of the grease gun barrel into the container of grease.
- Ensure that the nozzle is pointing up. d. Slowly and steadily pull the plunger back, drawing grease into the barrel. Be patient, as this process may take a bit of time.
Step 5: Reassemble the Grease Gun
Once you’ve filled the grease gun barrel with the desired amount of grease:
- Remove the grease gun from the container.
- Reattach the plunger securely to the grease gun barrel.
- Ensure that all components are tightly connected to prevent any leaks.
Step 6: Test Your Grease Gun
Before using the loaded grease gun on your equipment, perform a test by pumping a small amount of grease into a disposable container to ensure it’s functioning correctly. This step will help you avoid any surprises during your maintenance task.
Step 7: Lubricate Your Equipment
Now that your grease gun is loaded and tested, if you know how to load a grease gun without a cartridge then you’re ready to lubricate the components of your equipment or machinery as needed. Apply the grease precisely to the areas that require lubrication.

FAQs
1. Do grease guns need cartridges?
The gun is filled using packaged cartridges. These cartridges are convenient but are more costly than bulk loading and can negatively impact the environment because they are single-use. Unscrew the canister from the grease gun and pull back the plunger, locking it in place.
2. Are grease guns refillable?
Grease guns are designed to be reloaded easily with cartridges that slide into the canister.
3. How long is grease good in a grease gun?
For example, lithium grease is often identified as having a 12-month shelf life, while calcium-complex greases may have a shelf life of just six months – and this is under good storage conditions.
4. What are the disadvantages of a grease gun?
Grease guns can produce up to 15,000 psi per stroke (shot); however, most bearing lip seals are unable to withstand more than 500 psi. Because of this, grease guns can generate significant pressure and, if improperly used, can ultimately blow out the seals designed to protect the bearings from external contaminants.
Conclusion
While using cartridges makes loading a grease gun more convenient, knowing how to load a grease gun without a cartridge can be a lifesaver in emergencies or when cartridges are unavailable. With the step-by-step guide provided here, you can confidently load your grease gun manually and keep your machinery running smoothly.
Remember to choose the right grease, maintain cleanliness, and test your grease gun before putting it to work. By mastering this skill, you’ll be well-prepared for any maintenance task that comes your way.
