Stripped 727 Transmission cooling line

This just happened to me today. Putting my new transmission lines in and noticed the brass fitting was loose. Went to tighten it down and it wouldn't snug down. Backed it out and noticed that the first 1/4" of threads of the case were stripped out. I have access to a pipe tap to chase the threads. What are the chances of buying a new fitting and sealing it with some sort of epoxy sealer? Here's the offending fitting.
