Abstract:
A lower cost method of manufacturing a ferrule. The method includes cold heading a transition sleeve that includes an annular indented seat therein, providing a penetration sleeve comprising a plurality of inwardly directed and axially spaced apart attachment means for penetrating into a hose when said ferrule is radially inwardly deformed; and brazing the penetration sleeve to the annular indented seat in the transition sleeve. The resulting assembly is visually and functionally blended to become one-piece.
