This is not an exact answer to your question , but I have done similar repairs
- although non plumbing - in the past with JB Weld. I cleaned the female
threads well and then worked just enough JB into the threads. I put a light
coating of oil on the male threads, screwed them together and then let it set.
Unscrewing the first time can be a little difficult, but Iâ??ve always been
able to and have been able to reuse the threads.
While Iâ??ve never done a plumbing repair this way, I canâ??t see why it
wouldnâ??t work. My inclination would be to put a thin wrap of Teflon tape on
the male portion and then just leave it alone and hope for the best if I ever
had to remove it. Worst case, you are back to your original plan.
