A hose coupling ferrule and method of making the ferrule.

摘要

A ferrule (10) for use with a male stem which together define a coupling for flexible hose, the ferrule (10) including a sleeve (12) having an inside surface (14) from which extend a plurality of longitudinally oriented ribs (16) that are circumferentially spaced from each other. The ferrule (10) is preferably made by extruding a metal tube and forming a plurality of longitudinal ribs (16), circumferentially spaced from each other along the tube inside surface (14); and cutting the tube in desired lengths to define ferrules (10).

The invention also includes a hose coupling of the type having a male stem (38) with a ferrule locking collar (40) and a ferrule (10) as described above positioned substantially concentric with the stem (38) and having an end portion attached to the locking collar (40), the stem (38) and ferrule (10) defining an annular hose end receiving cavity, to a hose assembly with couplings attached to the two hose ends and each incorporating a ferrule (10) as described above and to a method of making a ferrule (10) for a hose coupling.
