It is important to understand that “crimping” a cap could result in an inadequate seal if not done properly.
Follow the steps shown below to achieve the best seal.
- You need a calibrated crimping tool (https://mtc-usa.com/Crimping-Tool) This means that the chuck has to be adjusted every 10 -15 crimps with the adjusting tool it comes with.
- After each crimp, test the seal to make sure it does not spin on the vial.
- After each crimp, make sure the septa is not dimpled or concave.
- After each crimp, make sure that the aluminum cap is evenly bent under the serum finish vial
