Choosing the right epoxy cartridge for your glue gun is essential for both the quality of your work and the safety of use. Cartridge size and fitting type make a big difference to performance and compatibility.
Cartridge Sizes and Fittings
Glue guns designed for epoxy cartridges typically accommodate industry standard sizes, most commonly 50ml. Many professional and hobbyist glue guns use a bayonet-type fitting. One popular option compatible with this system is the Araldite 2000 series. However, always double-check your glue gun’s specifications to ensure the chosen cartridge is supported.
- 50ml epoxy cartridges: Widely used in repair, assembly, and crafting tasks.
- Bayonet fitting: A common secure connection for cartridges, found on popular series like Araldite 2000.


How to Check Compatibility
A reliable way to determine compatible cartridges is to consult your glue gun’s instruction manual or manufacturer website. Key aspects to confirm include cartridge size (for example, 50ml) and cartridge base type (such as bayonet). If you’re using specialised accessories, like the Mixer Nozzle for Mixing Epoxy Glue, ensure they are also rated for your chosen cartridge and fitting.
When Compatibility Matters Most
Using a cartridge with the wrong size or interface can cause leaks, interruptions, or even damage your glue gun. For precise application and consistent mixing—especially in demanding repair or bonding tasks—ensure every component matches your equipment’s requirements.
