3M™ Static Mixing Nozzle
- Available for 50 mL and 200 mL / 400 mL cartridge formats
- Doubles as a cartridge storage cap between uses
- Automatic ratio metering through passive cascade mixing
Product Description
The 3M™ Static Mixing Nozzle is a disposable cascade mix/meter nozzle for use with 3M cartridges and manual or pneumatic applicators. As two-part adhesives, sealers, or foams pass through the nozzle, both components are automatically blended to the correct ratio; no manual mixing required. Once finished, the used nozzle can be left in place to cure and seal the cartridge outlet, protecting the remaining material until next use.
Key Features:
- Automatic ratio metering through passive cascade mixing
- Compatible with manual and pneumatic 3M applicators
- Works with a wide range of 3M two-component adhesives, sealers, and foams
- Disposable design eliminates mixing tool cleanup
- Doubles as a cartridge storage cap between uses
- Available for 50 mL and 200 mL / 400 mL cartridge formats
Typical Applications:
- Automotive body repair and panel bonding
- Plastic repair and structural bonding
- Industrial assembly and sealing applications
- Potting and encapsulation with two-component foam systems

Additional Information
3M™ Static Mixing Nozzle
Consistent, hands-free mixing for two-part adhesives, sealers, and foams.
The 3M™ Static Mixing Nozzle is a cascade mix/meter nozzle engineered for use with 3M cartridges and manual or pneumatic applicators. As two-part materials pass through the nozzle's plastic tube, the components are automatically blended to the correct ratio — eliminating manual mixing, reducing mess, and delivering a thoroughly mixed product at the point of application every time.
Designed for easy replacement, the disposable nozzle can also double as a storage cap when work is paused — sealing the cartridge until the next use. Compatible with a wide range of 3M two-component adhesives, sealers, and foams, the Static Mixing Nozzle is a practical consumable for automotive repair, bonding, and plastic repair applications.
Automatic ratio metering at the point of dispense
Two-part components are metered and mixed as they pass through the nozzle, ensuring the correct volumetric ratio is achieved without any manual measuring or mixing steps.
Disposable design for fast, clean changeovers
Nozzles are designed to be discarded after use, eliminating the need to clean mixing tools between applications. Simply replace with a fresh nozzle at the start of each job.
Doubles as a cartridge storage cap
Once dispensing is complete, leave the used nozzle in place and allow the material inside to cure and harden. This forms a seal that protects the remaining adhesive in the cartridge until next use.
Compatible with manual and pneumatic applicators
Engineered for use with standard 3M cartridges and compatible with both hand-operated and pneumatic dispensing guns, providing flexibility across different application environments.
Broad compatibility across 3M two-part products
Works with a wide range of 3M two-component adhesives, sealers, and foams, making it a versatile consumable across different products and applications on the same production line or shop floor.
Reduces cleanup time and waste
Eliminating manual mixing tools from the process simplifies post-application cleanup and reduces material waste associated with incorrect mixing, saving time on the shop floor.
Typical Applications
- Automotive body repair and panel bonding using two-part adhesives
- Plastic repair and structural bonding in automotive manufacturing and aftermarket
- General industrial bonding with 3M two-component structural adhesives
- Sealing applications using 3M two-part sealers in assembly environments
- Potting and encapsulation using 3M two-component foam systems
Why Mixing Quality Matters at the Point of Dispense
Achieving the correct mix ratio in two-part adhesive applications is critical to bond performance. The 3M™ Static Mixing Nozzle removes variability from the mixing step by handling metering and blending automatically — right at the nozzle tip, immediately before application.
Eliminate ratio errors from manual mixing
Manual mixing introduces the risk of incorrect ratios, leading to under-cured or off-spec bonds. The static mixing nozzle automatically meters both components to the correct ratio, removing this source of variability from the process.
Reduce inconsistency across operators
When mixing is performed manually, results can vary between operators and shifts. The static mixing nozzle delivers consistent results regardless of who is performing the application, improving process repeatability.
Minimize material waste from off-ratio mixing
Incorrectly mixed adhesive cannot be reworked and must be discarded. Automatic metering through the nozzle reduces the incidence of off-ratio material, helping to minimize adhesive waste and associated costs.
How the 3M™ Static Mixing Nozzle Works
The nozzle uses a passive cascade mixing design. No moving parts, no power source required. As the two components from the cartridge enter the nozzle, they are split and recombined through a series of internal mixing elements, resulting in a homogeneous, fully blended material at the outlet.
Variants and Compatibility
The 3M™ Static Mixing Nozzle is available in configurations for different cartridge sizes. Select the variant that matches your cartridge volume and dispensing application.
| Part Number | Cartridge Size | Nozzle Diameter | Material | Color | Pack Size |
|---|---|---|---|---|---|
| 08193 | 200 mL / 400 mL | 3/8 in | Plastic | Gold | 6 nozzles/bag, 6 bags/case |
| 08194 | 50 mL | — | Plastic | Opaque | 12 nozzles/bag |
| 38195 | 50 mL | — | Plastic | Opaque | 12 nozzles/bag |
Applicator Compatibility
The 3M™ Static Mixing Nozzle is designed for use with standard 3M two-component cartridges and is compatible with both manual and pneumatic 3M applicators. Always confirm that the nozzle part number matches the cartridge outlet size before use.
For use with 3M™ Scotch-Weld™ EPX applicators and Duo-Pak (DP) cartridges, refer to the 3M™ Scotch-Weld™ EPX Mixing Nozzle product line, which is specifically designed for those cartridge formats.
Storage and Maintenance Considerations
Proper handling of the nozzle and cartridge between uses helps preserve adhesive quality and prevents unnecessary waste.
Using the Nozzle as a Storage Cap
- After dispensing, leave the used nozzle attached to the cartridge outlet.
- Allow the mixed material inside the nozzle to cure fully. This hardens and seals the outlet.
- Do not attempt to reuse a nozzle that has been used as a storage cap. Replace with a new nozzle and purge before the next application.
General Handling and Storage
- Store unused nozzles in a clean, dry location away from direct sunlight and heat sources.
- Do not reuse nozzles that have been partially dispensed. Residual cured material inside the tube may affect mix quality.
- Inspect the nozzle tip before use to confirm the outlet is clear and undamaged.
- Dispose of used nozzles in accordance with applicable local regulations for adhesive waste.
Best Practices for Consistent Mix Quality
- Always use the correct nozzle part number for your cartridge size; mismatched nozzles may not seal correctly or may affect mix ratio.
- Replace the nozzle at the same time as starting a new application session, not mid-application.
- Ensure the adhesive or sealer is at the recommended application temperature before dispensing; viscosity affects flow through the mixing elements.
- For fast-curing adhesives, minimize idle time after attaching a new nozzle to prevent premature curing within the nozzle before application is complete.
