Corrugated pipes shield the internally routed lines from external influences and protect against damage. This increases the service life of the hose package. Solid and impact resistant plastics are used which, on the one hand, withstand pressure and impact loads, on the other hand have low abrasion and thus low wear due to rubbing, crushing and scratching.
For particularly stressed areas, additional wear parts are provided, which protect the corrugated tube from punctual wear and allow easy replacement without renewal of the entire hose package.
