ABSTRACT OF THE DISCLOSURE Provided is an improved flexible reinforced hose (50) having an inner core tube (2) for conveying fluids surrounded by two layers of tensioned fibrous reinforcement layers (4, 8) between which is disposed a spirally wound flexible polymeric tape (6) which is unbonded to either of the reinforcement layers and free to move relative thereto under flexing and pressure pulsing conditions and which is adapted to prevent moisture from penetrating core tube (2) from outside of hose (50). Other preferred embodiments include hose (60) in which a flexible polymeric tape (12) is applied longitudinally and hose (70) where the tape is a flexible polymeric metal composite tape (20) as well as hose (32) in which the reinforcement layers (32, 36) are oppositely helically wound.
