1. A process of securing a fitting to an end of a hose, the fitting having an axial extent, the process comprising:

  • crimping a first circumferential portion of the fitting from an initial diameter to a final crimping diameter to thereby define a first crimp; and

    ,in a next cycle, crimping a second circumferential portion of the fitting axially spaced apart from the first circumferential portion, the second circumferential portion being crimped from an initial diameter to a final crimping diameter to thereby define a second crimp; and

    ,performing at least a third crimping operation cycle on a third circumferential portion of the fitting from an initial diameter to a final crimping diameter, wherein the third circumferential portion is axially spaced apart from the first and second circumferential portions;

    wherein the third circumferential portion is located at an axial location such that once the third circumferential portion is crimped an uncrimped circumferential portion of the fitting remains between the second crimp and the third crimp, the uncrimped circumferential portion defining a bubble portion of the fitting after crimping the second circumferential portion; and

    ,whereby the fitting is secured to the hose by the crimps.
