The invention relates to a hose (1) for transporting steam, which is provided a) with an internal layer (2) and external layer (5) of rubber or rubber-like material and b) with a strengthening support system (3) which consists of glass filaments. The essential feature of this invention is that c) the glass filament over its entire cross-section and all basic building blocks (filaments, spun fibres) is impregnated all around with a rubber solution or rubber-like solution which d) is prevulcanised to an extent between 25% and 75%, in particular between 50% and 60%, prior to the final vulcanisation of the hose (1), and that e) the internal layer (2) of the hose is, as far as possible, steam-impermeable and f) the external layer (5) of the hose is, as far as possible, steam-permeable. s
