It's a good question Ben.

There's an interesting history behind AN fittings and the race car industry. AN stands for Aueonautical and Navy and they were a military standard used in WW2 on aircraft. They were a very robust fitting that could be quickly undone and serviced. You can imagine what they would have to go through on a war plane.

After WW2 there were a lot of mechanics returned from the war that then got involved in racing. There was a lot of military surplus materials out there including a heap of AN fittings. They found that these were great for racing for the same reasons they were good on fighter planes. Super reliable and easy to service.

As for the tapered seat holding pressure... Pretty much the same design is used in industrial hydraulics. They call them a JIC fitting (Joint Industry Council) They are dimensionally the same as AN fittings (and you can interconnect them) but JIC are usually made from steel. They are used on huge industrial machines like excavators with much higher hydraulic pressures.

Cheers
