PROBLEM TO BE SOLVED: To provide a transparent multiple tube excellent in chemical properties such as chemical resistance, oil resistance, solvent resistance, heat resistance, barrier properties or the like, having mechanical strength and flexibility withstanding repeated bending or the like and capable of transporting a plurality of liquids without being entangled and rubbed to be deteriorated. SOLUTION: The multiple tube is formed by bonding a plurality of flexible tubes side by side. The respective tubes 1 and 2 are constituted of a fluororubber type thermoplastic elastomer and the surfaces of the adjacent tubes are mutually bonded simultaneously with crosslinking. The cross-sectional contour of the tubes 1 and 2 can be made circular or triangular and the cross-sectional shape of the lumen of each of the tubes is circular. COPYRIGHT: (C)2004,JPO |
