Abstract
A gripping and sealing or coupling device particularly useful for heavy-walled tubular members includes a body member having first and second counterbores cooperatively receiving first and second ferrules therein. Radial expansion of the first ferrule on makeup of the device is limited by a cylindrical radial flange on the end of the ferrule and by radially dimensioning the first counterbore so that it is substantially less than a minor diameter of the threads of an associated coupling nut or on the coupling body. The holding forces of the ferrules is enhanced by limiting radial deformation while disassembly and reassembly of a coupling arrangement is readily facilitated.
