Grease Cartridges Explained: Types, Uses & Which One You Need (UK Guide)
If you're maintaining agricultural machinery, plant equipment, or workshop tools, choosing the right grease cartridge is essential. With different grease types available — including standard lithium, lithium complex, and specialist formulations — it’s important to understand what each one does and where it should be used.
This guide explains the different types of grease cartridges available in the UK, what they’re used for, and how to choose the right option for your equipment.
What Is a Grease Cartridge?
A grease cartridge is a pre-filled tube — typically 400g in the UK — designed for use with a grease gun. It allows you to quickly and cleanly apply grease to moving parts such as bearings, joints, and pins.
Grease cartridges are widely used across:
- Agricultural machinery
- Construction equipment
- Trailers and transport equipment
- Workshop maintenance
Using the correct grease cartridge helps reduce wear, prevent corrosion, and extend the life of your machinery.
Types of Grease Cartridges
Standard Lithium Grease
Standard lithium grease is one of the most commonly used general-purpose greases.
It is suitable for:
- Light to moderate load applications
- General machinery maintenance
- Workshop use
It provides good lubrication and corrosion protection, making it a reliable all-round option.
Lithium Complex Grease (Blue & Red)
Lithium complex grease is designed for more demanding applications.
- Ideal for agricultural and heavy-duty use
- Better resistance to water washout
- Higher load capacity
- Common in automotive and high-temperature environments
- Good for wheel bearings and transport applications
These greases offer improved performance compared to standard lithium grease, particularly under higher loads and temperatures.
How to Choose the Right Grease Cartridge
Choosing the right grease depends on how and where it will be used.
1. Load and Pressure
Heavy-duty machinery such as balers, loaders, and trailers require grease that can handle higher loads.
👉 Lithium complex grease is typically the better choice here.
2. Operating Conditions
If equipment is exposed to:
- Water
- Dirt
- Outdoor conditions
You’ll need a grease with strong resistance to contamination and washout.
3. Temperature
Higher operating temperatures (e.g. bearings, hubs) require grease that won’t break down under heat.
👉 Lithium complex grease performs better in these conditions.
4. Frequency of Use
For regular maintenance:
- A high-quality grease reduces the need for frequent reapplication
- Improves long-term protection
Are All Grease Cartridges the Same Size?
Most grease cartridges in the UK are 400g, which fits standard grease guns.
However, always check:
- Compatibility with your grease gun
- Cartridge fitting type
If you’re using a high-pressure or specialist grease gun, it’s worth confirming compatibility before purchase.
Common Mistakes When Choosing Grease
Using the Wrong Type
Using a low-spec grease on high-load equipment can lead to:
- Premature wear
- Increased maintenance
- Equipment failure
Mixing Greases
Different grease types don’t always mix well.
If switching grease type, it’s best to:
- Clean out old grease where possible
- Avoid contamination
Choosing Based on Price Alone
Cheaper grease can seem like a saving, but often leads to:
- More frequent application
- Reduced protection
Which Grease Cartridge Should You Use?
For most agricultural and heavy-duty applications:
👉 Blue lithium complex grease is typically the best all-round option
For lighter use:
👉 Standard lithium grease is usually sufficient
For higher temperature or automotive use:
👉 Red lithium complex grease is a strong choice

Final Thoughts
Choosing the right grease cartridge is a simple but important part of maintaining machinery properly. By selecting the correct grease for your application, you can reduce wear, improve performance, and extend the life of your equipment.
If you're unsure which grease is best for your setup, it’s always worth getting advice before making a decision.
