The 17647 Siphon Adapter is a fluid-intake connection component used on the SprayTech Airless EP2400 sprayer. It provides the interface between the siphon tube assembly and the pump inlet, allowing material to be drawn consistently into the sprayer.
A worn or damaged siphon adapter can allow air to enter the system, resulting in poor priming, pressure fluctuation, or inconsistent spray output. Replacing the adapter helps restore a tight seal and reliable material flow.
