How do I rebuild the seal bar(s)?

  1. Remove Teflon tape. Using acetone and a paper towel, clean the sealbar thoroughly to remove the adhesive residue, oil, and other contaminant so that the new Teflon tape will adhere to the surface of the seal bar.

  2. Remove the retaining screw and the wires. Leave the metal strips attached at both ends. Add new insulator tape to the bar, covering the top surface completely so that the wires do not make contact with the bar itself.
