    • A single-piece tube 20 is formed to include a hub 30 at first end 26 of the tube with a spout 44 extending from the hub to a second 28 of the tube. A tapered transition surface 38 extends between the hub 30 and the spout 44. A bevel 34 is formed at the base of the hub 30 on an outer surface 22 thereof adjacent the end 26 of the tube 20. An annular bead 36 is formed on the outer surface 22 of the hub 30 at a location spaced from the bevel 34 to define a space 46 between the bevel and the bead. A pair of bends 40 and 42 are formed in spaced portions of the spout 44. In another embodiment, an annular groove 50 is formed in the outer surface 22 of the hub 30 instead of the bevel 34 and the bead 36. An O-ring 48 can be located in the space 46 or the groove 50. The single-piece tube 20 formed with the hub 30 and the spout 44 can be assembled with a water mixing facility 56.
    • 单件管20形成为在管的第一端26处包括轮毂30,其具有从轮毂延伸到管的第二个28的喷口44。 锥形过渡表面38在轮毂30和喷口44之间延伸。斜面34形成在轮毂30的基部上,其外表面22邻近管子20的端部26.环形胎圈36形成在 轮毂30的外表面22在与斜面34隔开的位置处以在斜面和珠之间限定空间46。 一对弯曲部40和42形成在喷口44的间隔部分中。在另一个实施例中,环形凹槽50形成在轮毂30的外表面22中,而不是斜面34和凸缘36. O形圈 48可以位于空间46或槽50中。形成有轮毂30和喷口44的单件管20可以与水混合设备56组装。
