I have a T15 salt cell (Leslies replacement for a Hayward Aqua Rite). The threads are stripped on the male part of one end that connects to the system with a collar. I was able to muscle it back together to stop it from leaking when I cleaned the cell recently, but the threads are so mutilated I am sure I won't be able to do that again. The cell is not old. I don't want to replace it just for this. I was thinking of getting a soft 3" O-ring and seeing if that will seal it the next time. Suggestions?
