High pressure compact spiral hydraulic hose

A hose comprising:

• an inner tube of a single layer construction and defining a central longitudinal axis there through, and comprising a vulcanized rubber and a plurality of rod shaped particles orientated substantially parallel with the central longitudinal axis, wherein the plurality of rod shaped particles are carbon or graphite particles having carbon atoms which are bonded together in crystals aligned parallel to the long axis of each of the plurality of rod shaped particles, wherein the plurality of rod shaped particles is incorporated in an amount of 5% or less by weight, based upon total weight of the inner tube, and wherein particles comprised in the plurality of rod shaped particles have an average length of from about 1.5 mm to about 5 mm, and an average diameter of from about 5 to about 7 microns;
• a tie layer directly surrounding the inner tube;
• a first reinforcement layer surrounding the tie layer;
• at least a second reinforcement layer surrounding the first reinforcement layer;
• an interlayer interposed between the first and the second reinforcement layer, the interlayer bonding the first reinforcement layer to the second reinforcement layer;
• and,
• a cover surrounding the second reinforcement layer;
• wherein axial modulus of the inner tube is greater than a modulus of the inner tube in a perpendicular direction to the central longitudinal axis.
