The SprayTech 0551663 Siphon Tube is an OEM replacement rigid pick‑up tube designed for the fluid intake system on Advantage 600 and EPX2355 series sprayers. It extends from the pump inlet into the paint container, providing a direct path for material to be drawn into the fluid section.
Over time, the siphon tube can become cracked, warped, or clogged with dried paint. A damaged or obstructed tube can cause loss of prime, reduced flow, or air ingestion, leading to inconsistent spray performance. Replacing with this genuine tube restores proper suction, reliable priming, and consistent material delivery.

| Debris protection | Works with the inlet strainer to prevent large particles from entering the pump |

|---|---|
