Abstract: The invention relates to a process for preparing a fluid conduit comprising a mono-layer comprising a thermoplastic elastomer in an amount of at least 80 wt % with respect to the total weight of the mono-layer, comprising at least the 5 following steps: a. Melting a composition comprising at least a thermoplastic elastomer having a melt volume flow rate measured at 230° C. under a load of 10 kg (MVR 230° C./10 kg), according to IS01133 (2011) of at most 40 g/10 min and having a heat resistance of at least 250 hours at 175° C. at which the 10 elongation at break remains at least 100% as measured according to ISO 527 with a test speed of 50 mm/min; b. Forming a parison from the melt; c. Placing the parsion in a mold; d. Blow-up the parison against the mold; 15 e. Cooling down the mold, thereby obtaining the fluid conduit comprising the mono-layer. The invention also relates to a fluid conduit.
