A flexible hose is adapted to maintain its inner wall temperature above the dew point of air transported between a CPAP machines humidifier and mask, preventing condensation. An electrically energizable heating element forms a helical reinforcement member. The hoses first end has a standard CPAP soft end cuff. The second end comprises a special end fitting including: a support ring, electrical jack, and a specially shaped over-molded plastic cuff. The support ring has a ring portion threadably secured onto the helical reinforcing member, and a receptacle extending therefrom. A coaxial electrical jack is received within the receptacle, with the energizable heating element of the helix being wired to the prongs of the jack. A soft plastic cuff is molded over much of the ring portion and receptacle, to provide further integrity of the end fitting, while the remaining portion of the cuff conforms to the standard CPAP end cuff configuration.
