The present invention refers to a channelled tube for sinks, which comprises: (i) a threaded tube (1), which simultaneously and externally comprises a perpendicular peripheral outlet (1.1) located at one end portion thereof; where a smooth portion (1.2) is generated; an externally threaded surface (1.3) up to the final length thereof; two orifices (1.4) located at the end portion of the smooth portion (1.2), which are diametrically opposed therebetween; and a longitudinal channel (1.5) generated from each orifice (1.4); and an annular stop (1.6), which is generated by the formation of the outer threaded surface; and (ii) an extension thread tube (2) which length is transversally divided into two sections; where the first section (2.1) has a diameter higher than the second section (2.2); a perpendicular peripheral protrusion (2.3) is externally located at the end portion of the first section (2.1); and an inner thread (2.4) is located at the same end portion of the first section (2.1).
