there is a retainer ring behind the b nut that holds it on the hose end---the an fittings are of a higher quality thread with a radiused V and are aprox 40% higher strength than the non a/c AN type generally accepted fittings---commercial JIC type fittings are also 37* and with the same thread pitch but are not AN standards
