Ferrule, hose coupling, and methods of making same

摘要

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.

1. A method of manufacturing a ferrule, the method comprising:
cold forming a transition sleeve, the transition sleeve having an inner surface and an outer surface, a first end that is attachable to a stem, a second end that has an annular indented seat in the inner surface or the outer surface thereof, and a bell-shaped body extending from the first end to the second end; 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 to form a one-piece assembly.
