Abstract:
A method of repairing a leaking air conditioning hose assembly, the steps comprising:(a) cutting an old ferrule lengthwise and removing the old ferrule and an old hose from a bead lock fitting;(b) providing a new ferrule having an oval opening at one end of sufficient diameter to pass over a first annular flange on the bead lock fitting;(c) axially mounting the new ferrule over the bead lock fitting with the oval opening positioned between the first annular flange and a second annular flange adjacent the first annular flange, in a groove formed between the first and second annular flange;(d) turning the new ferrule with an edge of the oval opening positioned in the groove so that a smaller arc portion of the oval opening wedges into the groove to maintain the new ferrule in a locked position around the bead lock fitting;(e) providing a new air conditioning hose and inserting the new air-conditioning hose axially between an inner wall of the new ferrule and a top surface of the bead lock fitting; and(f) crimping the new ferrule to permanently retain the air conditioning hose between the new ferrule inner wall and a top surface of the bead lock fitting.
