ABSTRACT:
A hose construction for conveying water under pressure, a stem therefor and methods of making the same are provided, the hose construction comprising a flexible tubular hose having opposed ends, a metallic stem having opposed ends and having one of the ends thereof disposed in one of the ends of the hose, and a metallic tubular ferrule telescoped on the one end of the hose and being radially inwardly crimped toward the stem to compress the end of the hose between the ferrule and the stem, the one end of the stem having a plurality of annular spaced apart projections thereon and respectively having external peripheral surfaces embedded into the one end of the hose, the stem having an opening passing therethrough and defining an internal peripheral surface thereof, the one end of the stem terminating at an end edge thereof that is defined by the internal peripheral surface joining with the external peripheral surface of an adjacent annular projection the end edge defining a relatively large rounded end part on the stem that prevents the end part of the stem from being razored by water flow and from cutting into the hose when the hose is being bent relative to the stem adjacent the end part thereof.
