A method of the invention is aimed at improving the hygienic and sanitary characteristics of a hydraulic component intended to be installed in a hydro-thermo-sanitary plant or in waterworks, for example a pipe or a fitting. The above mentioned hydraulic component (1) comprises in particular a tubular body (2) and at least two inlet ports (3) at the opposite ends of the same. The method includes the following operating steps: applying a removable protective cover (10) to each of said inlet ports (3) of said hydraulic component, for preventing entrance of impurities, organisms and biological agents into the tubular body (2) introducing the hydraulic component (1) into an autoclave facility carrying out a cycle of treatment of the hydraulic component (1) in controlled temperature and pressure, inside the autoclave facility, for a predetermined period of time taking the hydraulic component (1) out from said autoclave facility. The invention comprises also a hydraulic component (1) having improved hygienic and sanitary characteristics, such as a pipe destined for hydro-thermo-sanitary uses or in waterworks, provided with a removable cover (10) and subjected to the above described method.La présente invention concerne un procédé visant à améliorer les caractéristiques hygiéniques et sanitaires dun composant hydraulique destiné à être installé dans une installation hydro-thermo-sanitaire ou dans des installations hydrauliques, par exemple un tuyau ou un raccord. Le composant hydraulique (1) mentionné ci-dessus comprend en particulier un corps tubulaire (2) et au moins deux orifices dentrée (3) aux extrémités opposées de celui-ci. Le procédé comprend les étapes opérationnelles suivantes : application dune couverture protectrice amovible (10) sur chacun desdits orifices dentrée (3) dudit composant hydraulique, pour empêcher lentrée dimpuretés, dorganismes et dagents biologiques dans le corps tubulaire (2) introduction du composant hydraulique (1) dans une installation dauto
