Abstract

A compressed-air brake line which comprises the following layers: I. an external layer made of a moulding composition which comprises at least 50% by weight of PA 11 and/or PA12, and II. an internal layer made of a moulding composition which comprises at least 50% by weight of polyamide whose monomer units comprise on average at least 8 C atoms, with the exception of PA11 and PA12, can be produced at low cost; it has high bursting strength even at elevated temperature, good low-temperature impact resistance and good ageing resistance.
