Cleaning after Use:

After each epoxy application, it is crucial to clean the mixing nozzle thoroughly to prevent resin buildup and clogging. Follow these steps:

  • 1. Remove the used nozzle from the dispenser.
  • 2. Wipe off any excess epoxy resin from the outside.
  • 3. Use an appropriate solvent recommended by the epoxy manufacturer to dissolve and remove hardened resin from the nozzle’s interior.
  • 4. Rinse the nozzle with clean water or solvent to eliminate any residue.
  • 5. Allow the nozzle to dry completely before storage.

Checking for Damage:

Regularly inspect the mixing nozzle for any signs of damage, such as cracks, deformities, or wear. Damaged nozzles should be replaced promptly to maintain proper mixing and dispensing performance.


Apply a small amount of lubricant, such as silicone grease or epoxy-compatible lubricant, to the exterior threads of the epoxy mixing nozzle. This helps to facilitate smooth attachment and detachment from the dispensing gun and prevents potential damage to the threads.

Proper Storage:

Storing epoxy mixing nozzles correctly is crucial to maintain their integrity and performance over time. Here are some key points to consider:

  • 1. Keep the nozzles in a clean and dry environment, away from direct sunlight and extreme temperatures.
  • 2. Store the nozzles upright or in a designated holder to prevent bending or deformation.
  • 3. Use protective caps or covers to shield the nozzle tips from contamination, dust, or damage during storage.
  • 4. Avoid placing heavy objects on top of the nozzles to prevent distortion.

Periodic Replacement:

Even with proper maintenance, epoxy mixing nozzles have a limited lifespan. It is advisable to follow the manufacturer’s recommendations regarding the maximum number of uses or time frame for nozzle replacement. Regularly monitor the condition of the nozzles and replace them when necessary to ensure consistent and reliable epoxy dispensing.


Proper maintenance and storage of epoxy mixing nozzles are essential for maintaining their performance and prolonging their lifespan. By incorporating these practices into your epoxy application process, you can ensure consistent results, reduce downtime caused by clogging or damage, and ultimately maximize the efficiency of your epoxy dispensing operations.
