Abstract
A fluid line includes a pipe of a multilayered plastics material. The pipe surrounds an interior space. The pipe has an inner, first layer of polyamide 9T (PA9T), a second layer of polyamide 12 (PA12), a third layer of polyamide 612 (PA612), a fourth layer of polyamide 6 (PA6) and an outer, fifth layer of polyamide 612 (PA612). The inner, first layer bounds the interior space. A fluid line that has a reduced dissolution of material, a reduced permeability to volatile substances, and nevertheless maintains sufficient mechanical properties for a connection to other components of a line, is hence provided.
