| Xemex X2-A5-7T Static Mixing Nozzle (10-Pack) | High-efficiency, multi-ratio blending | 7-element mixer for uniform mixing |
| Maven DMA50 Dispensing Gun (50ml Cartridges) | Standard 50ml cartridge dispensing | Consistent metering per plunger click |
| Dura-Fix Dual Cartridge Dispensing Gun | 2:1 cartridge systems | Designed for larger Dura-Fix cartridges |
MixPac 50ml Empty 1:1 Cartridges with Self-Venting Pistons
Best for small-to-medium jobs needing precise 1:1 mixing of epoxies, silicones, or urethanes. Each 50ml cartridge offers a combined volume of 1.7 oz, making metering straightforward for consistent bonds. The A-System flange ensures universal compatibility with standard dispensing guns and Bayonet 50ml mixing nozzles. The self-venting pistons allow air to escape during filling and seal on contact with resin, minimizing air pockets and improving repeatability. Limitations include the need for compatible nozzles and guns, particularly for high-volume production.
MIXPAC MFH F-System Static Mixing Nozzle
Better for workflows using 200–400 ml cartridge families with 1:1 or 2:1 ratios. This nozzle family supports five model configurations to match flow rate and pressure needs. The helix/round static design ensures thorough blending of epoxies, MMA, urethanes, and silicones, improving cure uniformity. A potential limitation is that nozzle compatibility depends on your cartridge size and system; verify the model before purchase.
Xemex X2-A5-7T Static Mixing Nozzle (10-Pack)
Choose this for high-performance, multi-ratio compatibility with A-System (bayonet) cartridges and both manual or pneumatic dispensers. The 7-element mixer geometry provides uniform mixing with fewer elements than traditional designs, supporting cleaner disbursement of epoxies, silicones, and urethanes. Best for users needing strong ratio control and consistency across different adhesives. Caution: ensure your dispenser supports 7-element nozzles and is not restricted to single-model configurations.
Maven DMA50 Dispensing Gun for 50ml AB Cartridges
This is an industry-standard dispenser designed for 50ml two-part cartridges, offering consistent metering with each plunger click. It is well-suited for shops and technicians needing predictable dosing and simple operation. Best for users who want straightforward, repeatable control without added complexity. Limitation: designed specifically for 50ml AB cartridges; larger or smaller cartridge sizes require a different gun model.
Dura-Fix Dual Cartridge Dispensing Gun
Best for manual 2:1 cartridge workflows, especially when using Dura-Fix 450 ml cartridges. This gun is designed to handle dual-cartridge setups efficiently and is a solid option for larger volume bonding projects. Use this if your process relies on 2:1 mixes with larger cartridge sizes; avoid this if you require compact, lighter-weight tools or 1:1 ratios.
Buying Guide: Key Considerations For 2 Part Dispensing Systems
- Cartridge compatibility: Confirm the cartridge size (50 ml, 200–450 ml, etc.) and the flange type (A-System/Bayonet) to ensure the gun and nozzle pair correctly.
- Mix ratio range: Decide whether you need 1:1, 2:1, or multi-ratio capabilities. Some nozzles and guns support multiple ratios, offering flexibility for different adhesives.
- Dispensing precision: Look for self-venting pistons or metering mechanisms that minimize air pockets and ensure consistent flow across cycles.
- Flow rate and nozzle options: Multiple nozzle configurations help tailor the flow to your application, balancing cure time and throughput.
- Ease of maintenance: Consider nozzle accessibility and cleaning needs, as clogged nozzles degrade accuracy over time.
- Ergonomics and handling: For high-volume use, select guns with balanced weight, comfortable trigger action, and secure cartridge seating.
Frequently Asked Questions
- What is a 2-part dispensing system? It is a setup that meters and dispenses two reactive components (A and B) in a precise ratio for adhesives like epoxy or silicone.
- What does an A-System flange mean? It indicates compatibility with standard 50 ml, or Bayonet-style cartridges and mixing nozzles used in many dispensing setups.
- Why are static mixing nozzles used? They ensure thorough blending of the two components as they exit the cartridge, leading to uniform cure.
- Can these guns handle 1:1 and 2:1 ratios? Some models support both; verify model-specific ratio capabilities before purchase.
- Are 50 ml cartridges suitable for production lines? They work well for small to medium volumes, quick prototyping, or repair jobs, but larger cartridges boost throughput for heavy production.
- What should I consider when choosing a nozzle? Match the nozzle to your cartridge size, desired flow rate, and mix ratio to maintain consistent bonding performance.
