<p>The present invention is an improved hydraulic fitting (10) of the type having a stem (12) including a hose insert portion, and a collar support portion. The fitting further has a mating connection portion, and a collar (16) having, a torque communication portion (18), a ferrule support portion, and an inner periphery extending through the ferrule support portion and the torque communication portion. The fitting is improved by the collar support portion including knurling (40) and an axial stop ring (28). Further, the torque communication portion (18) of the collar (16) is staked such that the inner periphery extending through the torque communication portion (18) communicates with the knurling (40) of the collar support portion of the stem in a relatively non-rotational manner. Also, the ferrule support portion of the collar (16) is staked such that the inner periphery extending through the ferrule support portion communicates with the axial stop ring (28) of the stem (12) in an axial movement limiting manner.</p> |
