I was wondering if anyone had come up with new seals for inside the flapper boxes. Just trying to make it so I get heat when I want it, and no heat when I dont.

After looking at the flappers, it looks like they had some type of seal on them at one point, but not much left after 35 years. And, I have already heard the usual comments of "Buy headers and a jacket"

Helper springs is a great idea. I've asked this same question- think it was in August. In my flappers, the asbestos (I'm guessing) ring had come lose, so right now I have bad sealing too. I've adjusted and readjusted the cables too. In fact, it leaked just as much hot air with the cables disconnected. There has to be some kind of high temp capable stuff we can use to make new ones. Where are the fabricators? Hey out there! Bruce, or Engman, or Dr Evil, or ...

I was even thinking maybe a ring of high temp silicone would make a good sealing surface. I will try the helper springs first and see what they do.
