This upgraded suction tube kit is specially designed for Graco Magnum stand model paint sprayers, including Project Painter Plus X5, X7, ProX17, and ProX19. It solves the common problems of paint leakage and hose rupture in traditional suction tube sets, making it an ideal replacement for worn or aging parts. The kit adopts an enhanced tight-sealing joint structure, which effectively prevents paint leakage during the spraying process and ensures the continuity and efficiency of the oil suction process. Made of high-grade elastic rubber, the feed and return pipes can withstand high working pressures (up to 1200 PSI) and resist corrosion from acid, alkali, and other components in paint, suitable for long-term use in complex painting scenarios (such as indoor wall painting, outdoor furniture spraying, and industrial equipment coating). In addition, the soft and flexible material allows the hoses to adapt to various bends and twists, facilitating flexible layout in narrow or irregular working spaces. The kit includes all necessary components (suction tube, drain tube, strainer, and clips) for one-stop replacement, and the installation and disassembly process is simple—no professional tools are required, saving time and labor costs for both professional painters and DIY enthusiasts.
