These are not AN sizes but Metric.
Measure the outside dimensions of the threads. That is the fitting size.
Almost always the thread pitch is 1.50, so a fitting with 22.0mm outside dimension would be a M22x1.5 which is standard DN13 size.
If you are ordering Braided SS hose then you will need adapters from Metric to AN for both the supply & the return.
I have a few different Metric to AN adapters, depending on size needed.
I know I have both the early (M26x1.5) & late (M30x1.5) 911 sizes.
The DN 13 is smaller that I keep in stock, but it can be ordered.
