One of the reasons I wanted to use a Helium leak detector was because using this method a person can determine if the leak is in the area of the metal flange at the front of the tube, or if the leak is in the neck end where the pinch off and lead wires exit. I am hoping that we will be successful in sealing the leaker 15G, but only time will tell. And it may take a long time. We are talking about very small leaks. The kind that may take years to let enough air ento the tube to make it go bad. My bet is that we will be successfull initially on the leaker tube, and that it may be a long time until, if and when, it takes on enough air to go bad.


I'm fascinated by this but have zero knowledge so please don't jump up and down on me too hard if the following question makes no sense. If it can take years for a minute leak to let in enough air for the tube to go bad, are there any chemicals or metals that could be introduced into the tube during the rebuild that would react with any oxygen that finds its way into the tube and bind it? OK; I'll put this in to save you the trouble
