The present invention is an improved hydraulic fitting of the type having a stem including a hose insert portion, and a collar support portion. The fitting further has a mating connection portion, and a collar having, a torque communication portion, 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 and an axial stop ring. Further, the torque communication portion of the collar is staked such that the inner periphery extending through the torque communication portion communicates with the knurling of the collar support portion of the stem in a relatively non-rotational manner. Also, the ferrule support portion of the collar is staked such that the inner periphery extending through the ferrule support portion communicates with the axial stop ring of the stem in an axial movement limiting manner.
An improved hydraulic fitting of the type having a stem including a hose insert portion, and a collar support portion, having a mating connection portion, and a collar having, a torque communication portion, a ferrule support portion, and an inner periphery extending through said ferrule support portion and said torque communication portion, the improvement comprising:
