Anyone know where I could find the specifications for a SAE 37' AN fitting dash 12 = > 1 1/16 - 12. I have a job that I need to turn a dash 12 female thread into the end of a bung. I have found porting tools for milling but I don't want to $$by one since I am turning this part. I thought maybe there was a mil spec or AN spec with the dimensions and tolerances for the chamfer and o-ring relief.
