Every cell on the sheet is read back from the same 110-row database the size pages print, through the same formatters, so a figure here is byte-identical to the figure on the fitting page it came from. The columns are:
- Location
- Fitting
- Standard
- Half
- Qty
- Thread
- Thread diameter
- Seat
- Working pressure
Where a cell has no published value it prints as a stated gap with a numbered footnote saying which source stops there - never as a blank, and never as an interpolation. Working pressure in particular is published per size by some manufacturers and not by others, and a sheet that filled those cells with a plausible number would be worse than a sheet with a hole in it.
The sheet is a reference aid for identification and ordering. Confirm every pressure rating against the manufacturer specification for the exact part before a system is charged.
