How to Choose the Right Dual Cartridge Gun
Choosing the right dual cartridge gun depends on cartridge size, mixing ratio, material type, working frequency, and dispensing method. Different applications may require different gun structures, from compact manual models for small cartridges to battery-powered and pneumatic options for repeated or industrial dispensing work.
1. Choose by Cartridge Size
Start by confirming the cartridge capacity you need to use. Small 50ml and 75ml cartridges are suitable for precise repair, bonding, and small-volume adhesive applications. Larger 200ml, 400ml, 490ml, 585ml, and 600ml cartridges are more suitable for construction, sealing, epoxy dispensing, and industrial adhesive applications.
2. Check the Mixing Ratio
Dual cartridge guns are available for different mixing ratios, including 1:1, 2:1, 3:1, 4:1, 5:1, and 10:1. The correct ratio depends on the two-component material and cartridge design. Before ordering, confirm the cartridge ratio to ensure the plungers match the material system.
3. Select the Right Power Type
Manual dual cartridge guns are suitable for standard applications and flexible daily use. Battery-powered dual cartridge guns help reduce hand effort during repeated dispensing work. Pneumatic dual cartridge guns are better suited for higher-volume or continuous dispensing tasks where air-powered output is preferred.
4. Match the Material and Application
For epoxy, adhesives, sealants, repair compounds, and other two-component materials, the gun should match both the cartridge format and the working environment. Construction repair, window sealing, shower sealing, bonding, assembly, and industrial dispensing may require different sizes and structures.
5. Confirm Color, Material, and Custom Needs
Standard models are available in off-white, blue-black, yellow, black, and blue-black color options. Materials include PP+PA, nylon alloy, and metal-plastic structures. For bulk orders, custom colors, branding, and packaging can be discussed based on project requirements.

Dual Cartridge Caulking Gun FAQs
What is a dual cartridge caulking gun used for?
A dual cartridge caulking gun is used for dispensing two-component materials such as epoxy adhesive, AB glue, structural adhesive, repair compounds, and two-part sealants. It is commonly used in bonding, construction repair, industrial assembly, window installation, automotive repair, and professional sealing applications.
What is the difference between a dual cartridge gun and a standard caulking gun?
A standard caulking gun is designed for single-component cartridges, while a dual cartridge gun holds two cartridges and dispenses both materials at the same time. Dual cartridge guns are used when the adhesive or sealant needs two separate components mixed together through a static mixer nozzle.
Which mixing ratios are available for dual cartridge guns?
Dual cartridge guns are available for different mixing ratios, including 1:1, 2:1, 3:1, 4:1, 5:1, and 10:1. The correct ratio depends on the cartridge design and the two-component material system. Before ordering, buyers should confirm the cartridge capacity, ratio, and plunger structure.
How do I choose between a 1:1, 2:1, and 10:1 dual cartridge gun?
A 1:1 dual cartridge gun is commonly used for equal-ratio epoxy and two-part adhesives. A 2:1 gun is suitable for adhesive systems where one component volume is twice the other. A 10:1 dual cartridge gun is used for high-ratio materials that require a smaller amount of hardener or catalyst. The gun must match the cartridge ratio exactly.
What cartridge sizes can dual cartridge caulking guns support?
Dual cartridge guns can support different cartridge sizes, such as 50ml, 75ml, 200ml, 250ml, 360ml, 375ml, 380ml, 390ml, 400ml, 450ml, 490ml, 585ml, and 600ml, depending on the model. For B2B orders, it is best to provide your cartridge size and mixing ratio so the correct applicator can be recommended.
Can dual cartridge guns be used with static mixer nozzles?
Yes. Dual cartridge guns are commonly used together with static mixer nozzles to mix two-component adhesives and sealants during dispensing. The mixer nozzle should match the cartridge outlet, material type, and required mixing performance.
Are manual dual cartridge guns suitable for industrial use?
Manual dual cartridge guns are suitable for repair work, field installation, small-batch bonding, and flexible daily use. For repeated dispensing, high-volume production, or thicker materials, battery-powered or pneumatic dual cartridge guns may be more suitable because they reduce hand fatigue and improve dispensing consistency.
When should buyers choose a pneumatic dual cartridge gun?
A pneumatic dual cartridge gun is suitable for factories, workshops, production lines, and high-volume adhesive dispensing. It uses compressed air to provide more consistent output, which is useful for repeated bonding, sealing, and industrial assembly applications.
Do you support OEM or private label dual cartridge guns?
Yes. OEM and private label options may include custom colors, logo printing, packaging design, and bulk supply for distributors or tool brands. The available customization depends on the selected model, order quantity, and production requirements.
