  • Coupling device and method for tubular elements
    Patent number: 5064225
    Abstract: Coupling device and method for joining together tubular elements such as sections of aluminum tubing. The device comprises a coupling sleeve having conically tapered walls of diameters corresponding to the diameters of the tubular elements to be joined together. The tubular elements and the sleeve are pressed together to form a rigid structure in which the tubular elements are aligned axially of each other and the walls of the cooupling sleeve are in tight frictional engagement with the walls of the tubular elements.
