AN Thread Sizes
AN (Army-Navy) Sizes were established by the Aerospace industry years ago and were designated O.D.
of the rigid metal tube that each size fitting is used with. (The chart will clarify this point.)
The numbers assigned equate to the O.D. (outside diameters) of the tubing in 1/16.
Since tubing and hoses are to be found with assorted wall thicknesses, we can now understand that
the designated size number does not necessarily tell you how large the inside diameter will be.
(For example, the inside diameter of a size 6 hose end is nearly as large as the inside diameter
of some manufacturers -8 hose ends.)
Each AN size number has its own standard thread size which can be seen in column three of the chart.
Again, these are the same thread sizes that have been used in aircraft and industrial applications
for many years.

NPT Thread Sizes
Some of the most popular adapter fittings are AN to NPT adapters. While many variations are offered,
column four in the chart shows which AN size corresponds to each NPT size when inside diameters
(flow dimensions) are considered.
All hose ends are designed to provide little or no restriction when used with the corresponding AN fitting size.
There are a number of Metric and British Standard Pipe threads to AN fitting adapters.
