An improved crimped swivel fitting (10) for a gasoline hose (11) is disclosed. The fitting is a three-piece assembly (10). A male stem (30) is provided with a shoulder (39) at one external end (31A) and a series of barbs (35) at the opposing end (31B). A swivel nut (50) with an external threading, is slid over the stem barbs (35) and abuts directly against the shoulder (39). The barbed stem end (31B) is inserted into a hose (11) to which a ferrule (60) with internal notching (64) has already been attached. An internal shoulder (63) of the ferrule (60) rests in a groove (33) on the stem (30) and directly abuts against a shoulder (55) of the swivel nut (50). The ferrule (60) is crimped onto the stem (30), thereby securing the fitting to the hose, and locking the swivel nut (50) onto the assembly (10).
L'invention concerne un raccord pivotant serti (10) amélioré destiné à un tuyau d'essence flexible (11). Ce raccord est un ensemble (10) en trois pièces. Une tige mâle (30) comporte un épaulement (39) à une de ses extrémités extérieures (31A) et un ensemble de crans (35) à l'extrémité opposée (31B). On fait glisser un écrou de raccord (50) à filetage extérieur sur les crans (35) de la tige, pour qu'il vienne buter directement contre l'épaulement (39). On introduit l'extrémité (31B) de la tige crantée dans un tuyau flexible (11), auquel on a auparavant fixé un manchon (60) à encoches intérieures (64). Un épaulement intérieur (63) du manchon (60) repose dans une rainure (33) de la tige (30) et vient directement buter contre un épaulement (55) de l'écrou de raccord (50). Le manchon (60) est serti sur la tige (30), fixant ainsi le raccord au tuyau flexible, et bloquant l'écrou de raccord (50) sur l'ensemble (10).
