13/16” inverted flare is for 7/16” tubing which is the stock size. I couldn’t find 7/16” tubing so, I opted to use 3/8” which is readily available. At the time, I couldn't find a 13/16” inverted male flare to 3/8” tube fitting, thus the reason for fabricating one.
If you have a source, please post it so others can benefit from it.
I was going by this post in your earlier thread:

I pictured buying a few adaptors and installing CuNi tubing to make the connection. Well that seems to be much easier said than done, as “No1300” found out, and I am finding out…...“

I CAN locate an INV flare tube nut which has 11/16 thread and fits 3/8 OD tube. Are you saying you need a fitting that is 13/16 thread and fits 3/8 tube?
