A seal for a fuel filler nozzle is disclosed which is installed in the filler neck of a fuel tank of a motorized vehicle and includes a seal ring of elastomeric material and a sealing lip which sealingly, fittingly and elastically engages a fuel filler nozzle inserted into the filler neck. The seal ring is connected to a conically tapered seal carrier which functions as a conical nozzle guide during insertion of the nozzle into the filler neck. The seal carrier is made of a single piece and is fittingly and rigidly connected to the seal ring. The filler nozzle seal is economically manufactured due to the small number of parts involved and functions reliably over a long period of use.

L'invention concerne une garniture pour lance de remplissage de carburant. La garniture est installée dans le goulot de remplissage du réservoir de carburant d'un véhicule automobile et comprend une rondelle de matériau élastomère ainsi qu'une lèvre d'étanchéité qui s'adapte parfaitement, de manière élastique autour d'une lance de remplissage insérée dans le goulot de remplissage. La rondelle d'étanchéité est raccordée à un porte-joint tronconique qui sert de guide à la lance pendant l'insertion de celle-ci dans le goulot de remplissage. Le porte-joint est monopièce et raccordé de manière serrée et rigide à la rondelle d'étanchéité. La garniture de la lance de remplissage est fabriquée de manière économique en raison du petit nombre de pièces qu'elle comporte et elle fonctionne de manière fiable pendant un usage prolongé.
