ABSTRACT OF THE DISCLOSURE An ultra-high pressure hose assembly capable of withstand- ing sustained internal fluid pressures exceeding 60,000 psi is disclosed herein and consists essentially of an innermost tubular core, a plurality of successive tubular layers and an outer containment sleeve. The innermost tubular core and containment sleeve are designed to add substantially no structural integrity to the overall assembly but rather function only as a fluid barrier and containment means for the tubular layers respectively. The outer tubular layers serve as structural members of the overall assembly and respectively consist of individu- al bands which are alternately helically wound around and directly against the layers immediately below them at predetermined helix angles. Each band in turn consists of a number of separate steel wires which have opposing flat sides and which are positioned in unconnected edge to edge relationship to one another so as to form the band. In addition, the bands of successive layers, starting with the innermost tubular layer, define successively increas- ing helix angles, whereby to cause all of the layers to share substantially in the overall loading of the assembly at its operating pressure.
