Hi,

I would first try running a sharp tap 7/16-20 and straighten up the threads. the CVA-170 seals on a O ring not on the threads and this is your best option.

I would think it would be a minor repair and required only a log book entry.Or not.

1/8 NPT is the next option or have someone tig weld a bead and re tap the hole.

Or call the experts at:
