Can't fix stupid
I think the first step of a double flaring tool does the same thing
One thing i haven't done yet, double flare.
Closest thing was a 37 degree flare for AN fittings.
And this is the tool: https://www.ebay.com/itm/274048437564
I paid much less for it years ago (iirc less than $30 as used on amazon), I nearly bought a new one since it's so freaking handy.
Then i got the bright idea: measure the freaking ball bearings and see if i can't order new ones.
Now i have plenty of spares should they decide to separate from the tool again.
