I've been vaping since January and I started rebuilding atomizers for the tanks in the subject in February. So far I've been able to get a consistent 1.8 to 2.0 ohm builds and I use organic cotton as my wick. All the parts have been holding up well but this past week I noticed that on a rebuild that the little grommet that goes in the bottom had 2 burnt spots on it. They seem to be surface burns and the rebuild I did with it works fine. What I'm concerned about is that eventually the rubber pieces on the atomizers are going to become unusable. This includes the grommet I mentioned, plus the seal that goes over the stem. Due to some losses of parts on other atomizers I have a few back up parts. I do not, however, have any of the rubber grommets that separate the coils for pos/neg. Does anyone know where I can get extra grommets and the stem seal? I can just buy additional atomizers but if I could find a source for the parts that wear out I could get a great deal more mileage out of the existing atomizers I have. The metal parts appear to hold up just fine. Any help will be appreciated!
