The corrugated tube (10) has end sections (12, 18) that are uncorrugatedly formed, where the corrugated tube is made of thermoplastic plastic material such as perfluoralkoxy copolymer with high fluorine content. A middle section (16) comprises an oblong formed inner volume (26) with a major cross-section surface (24). The end section (12) comprises another oblong formed inner volume (20) with a minor cross-section surface (22) that is larger than the major cross-section surface of the inner volume (26) of the middle section. |
