The Vape-Jet needle will need to be changed if it is bent during filling, or if a batch of cartridges being filled require a different needle length than the previous batch.

Step-by-step guide

Needed tools:

  1. Needle-nose pliers

Needed materials:

  1. New injection needle


  1. Remove the old injection needle by gripping the needle luer-lock base with the needle-nose pliers and twisting counterclockwise (if viewing up the needle from the Vape-Jet base).

  2. Select the appropriate length of new injection needle.

  3. Grip the luer-lock base of the new injection needle with the needle-nose pliers, and insert into the luer-lock of the needle holder; gently twist clockwise 1/4 turn to secure the new injection needle.
