Abstract:
1. A hose fitting comprising: a body having a connection portion configured for connection to an external component, a tubular nipple portion configured for insertion into an end of a hose, and a union portion joining the nipple portion to the connecting portion; a socket having a union portion joined against relative axial movement to the union portion of the body and having a crimp portion extending from the union portion of the socket, the crimp portion surrounding at least a portion of the tubular nipple portion of the body; and a swage collar having a tapered inner surface that radially inwardly deforms the socket when the swage collar is moved axially over the socket to retain a hose between the socket and the nipple portion of the body; wherein the crimp portion of the socket is joined to the union portion of the socket by an annular reduced thickness wall portion, whereby the transfer of torsional forces acting on the crimp portion of the socket relative to the union portion of the socket is reduced; and wherein the socket has an inner surface that is radially inwardly tapered going in a direction of the union portion of the socket in an uncrimped state of the crimp portion.
