This was the style with no seals also - just three o rings. There are LOTS of metal sections there (maybe 8 total). I just noticed it was leaking tonight when I was choring. I am hoping that it just needs tightening, but I have a feeling it is the opposite.
This is the unit that I had to work on and put in some parts from a donor. It was originally a low power unit but I had to put the high power star and center in it as a replacement.
I may try using some Permatex Hi-Tack on it instead of RTV. That is tomorrow nights adventure. I will post back.
