Abstract

Le tuyau de carburant haute pression (2) comprenant au moins une tête de raccordement (21) venue de matière et située à une extrémité du tuyau, la tête de raccordement ayant dans sa partie avant une portée sphérique d'interface de liaison étanche (210) et une collerette centrale (212) formant une butée d'appui pour un écrou de serrage. Conformément à l'invention, la tête de raccordement comprend une collerette cylindrique de centrage (211) qui prolonge la portée sphérique d'interface de liaison étanche.The high pressure fuel pipe (2) comprising at least one integral connection head (21) located at one end of the pipe, the connection head having in its front part a spherical surface of sealed connection interface (210 ) and a central flange (212) forming a bearing stop for a tightening nut. According to the invention, the connection head comprises a cylindrical centering collar (211) which extends the spherical surface of the sealed connection interface.
