PROBLEM TO BE SOLVED: To provide an aqueous medium transporting rubber hose having a superior mechanical feature and high insulation quality as well as a superior workability at the time of its manufacture.SOLUTION: This invention relates to an aqueous medium transporting rubber hose having a rubber layer vulcanized with rubber composition including ethylene-propylene-diene copolymer rubber (A), softening agent (B), carbon black (C), and cellulose fiber (D). An average fiber diameter of the cellulose fiber (D) is 2 to 1000nm, an average fiber length is 0.1 to 1000 μm, inclusion amount of the softening agent (B) is 10 to 200 pts.mass in respect to 100 pts.mass of ethylene-propylene-diene copolymer rubber (A), inclusion amount of the cellulose fiber (D) is 2 to 35 pts.mass, inclusion amount of carbon black in the rubber composition is 10 to 33 mass%, and a cubic volume intrinsic resistance of the rubber layer is 10to 10&OHgr;*cm.SELECTED DRAWING: Figure 1 |
