Notes from the standard
- Dash number: tube size alone (pipe thread 1/8 or the size shown), or tube size then pipe size in sixteenths where it differs (6-8 = 3/8 tube, 1/2 pipe).
- Cells printed once across several rows in the listing are repeated on each row they span.
- Rows were resolved from the page image; G for -10-12 to -16 and M for -7/-8 and -12-8/-12 are single cells spanning rows.
