The disclosure relates to tube or hose (1, 10) including a plurality of coaxially arranged sheaths (2, 3, 4, 5, 6, 7, 8, 12, 13) that are bonded together. The multilayered tube or hose (1, 10) includes at least: a force bearing sheath (2), an abrasion resistant sheath (12), and an adhesion promoting layer (13) that is arranged between the force bearing sheath (2) and the abrasion resistant sheath (12) and that increases the bonding force between said force bearing sheath (2) and said abrasion resistant sheath (12). The adhesion promoting layer (13) includes a mixture of 55 to 85 parts of acrylonitrile butadiene rubber, 5 to 25 parts of styrene butadiene rubber, 5 to 25 parts of ethylene propylene diene monomer, 75 to 125 parts of carbon black N990, 30 to 90 parts of calcium magnesium carbonate, 5 to 15 parts of zinc oxide, 5 to 25 parts of magnesium-aluminium hydroxycarbonate, 20 to 95 parts of resin package blend, 2 to 10 parts of N-(1.3-dimethylbutyl)-N′-phenyl-p-phenylendiamine, 5 to 15 parts of triallyl cyanurate, and 0.5 to 5 parts of a vulcanizing agent.
