A hose coupling (20) and method of manufacturing same are disclosed. The hose coupling includes a stem (28) to which is staked a ferrule (30). The stem includes a radially inwardly directed groove (44) into which a radially inwardly directed wedge (56) of the ferrule is staked. The wedge includes a width that is greater than the width of the groove before staking. Moreover, the groove includes a bottom surface from which first and second canted sides (50) extend at a first angle, while the wedge includes an inner surface from which first and second canted sides (66) extend at a second angle. The first and second angles are not parallel but within five degrees of one another. The stem and ferrule form at least six distinct regions of surface contact to guard against rotation of the ferrule relative to the stem. |
