The invention relates to a pressurized fluid conduit comprising a mono-layer of a semi-crystalline thermoplastic material that has a hardness of between 50 and 65 Shore D and a modulus at 150° C. of at least 60 MPa. Advantages of such a conduit are simple manufacture, easy handling and assembling at for example room temperature, while still requirements regarding burst-pressure and deformation at elevated operating temperatures are fulfilled. Other important advantages include significant savings in material use and better vibration and noise damping. The invention also concerns the use of 2 semi-crystalline thermoplastic material with a hardness of between 50 and 65 shore D and a modulus at 150° C. of at least 60 MPa for making a mono-layered pressurized fluid conduit via an extrusion moulding process, and a process for making said conduit.
