Abstract
Processes for securing a fitting to a hose end, and a hose assembly produced thereby. The fitting has an interior portion, exterior portion, and cavity therebetween. An end of the hose is located within the cavity and compressed between the interior and exterior portions. The exterior portion of the fitting has at least first and second circumferential crimped portions axially spaced apart along the fitting length, and first and second portions of the hose are compressed within the first and second circumferential crimped portions. The exterior portion of the fitting has an annular-shaped bubble portion between the first and second circumferential crimped portions. The bubble portion has a diameter larger than diameters of the first and second circumferential crimped portions, and the hose has a portion radially expanded into an annular-shaped cavity surrounded by the bubble portion as the hose is compressed at the first and second portions thereof.
