Abstract
A hose end coupling unitary, one-piece radially crushable ferrule has a crushable socket portion, a deformable attachment portion, and a work hardened torque communication portion defined between the socket portion and the attachment portion. The torque communication portion may be formed in the unitary one-piece radially crushable ferrule, contiguous with the socket portion and the attachment portion. Corners of the torque communication portion may be strengthened and/or the torque communication portion work hardened by disposing a die set about the formed torque communication portion and pressing the torque communication portion into the die set, strengthening corners of the torque communication portion and work hardening the torque communication portion. A mandrel having a desired internal shape of the torque communication portion may be deployed inside the torque communication portion during pressing.
