Abstract
The steps include cutting an old ferrule and hose from a bead lock fitting, inserting axially a new ferrule having an oval or irregular opening over the bead lock fitting and wedging an edge of the oval opening between two annular flanges on the bead lock fitting. Thereafter, a new hose is inserted axially between the ferrule and bead lock fitting and the ferrule is crimped to the hose to permanently lock it into position over the bead lock fitting.
Claims3
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.

- (b) providing a new ferrule having an opening at one end of sufficient diameter to pass over a first annular flange on the bead lock fitting;
- (c) cutting an arc in an edge of the opening, the arc having a diminished diameter conforming to the diameter of a groove formed between the first annular flange and a second adjacent annular flange;
- (d) turning the new ferrule so that the edge of the opening containing the arc with the diminished diameter is wedged in the groove so that the ferrule will be held in an axially configuration 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.
