Found this information for you:
The AN (Army-Navy) standard was established many years ago by the US military to set a common measurement for hose and fittings. It designates the outside diameter (O.D.) of the ridged metal tube that is compatible with each size of fitting. Still today, this AN dash standard is the benchmark measurement for military, industrial and the performance hose applications. These dash sizes are
expressed as the numerator of the fraction, with the denominator always
being 16. For example, a -04 port is 4/16 or 1/4-inch.
Metric..............AN-......US Hose ID
Size Hose ID...............Inches
