ABSTRACT:
A hose end unit comprises a reinforced hose end portion having at least an inner cylindrical elastomeric liner and a reinforcement layer and an end fitting being of the kind comprising an insert to enter into the end portion of the hose and a ferrule to surround the end portion of the hose. A plurality of radially inward projections are provided on the ferrule and the ferrule is swaged around the insert so that the hose end portion is gripped between the insert and the ferrule by the projections. The extrusion gap, as herein defined, is sufficiently narrow to substantially prevent flow of the elastomeric liner in the axial direction in use. Furthermore, the space between the ferrule and the insert in between two extrusion gaps is completely filled and the elastomer is compressed into cells delimited by the extrusion gap.
