should be #3 SAE flair, so 3/8-24 is the thread size.

Thanks for that advice. I had to remove the stainless pipes from the aluminium frame and as a result the thread came with the pipe removal. I plan to put a helicoil to repair the thread. I note that the pipe is not flaired but has a kind of ss washer clamped to it in place of the flair. Is the helicoil approach achievable.
