The SprayTech 451-241 Siphon Tube is the intake component that draws coating materials from containers into the sprayer system on compatible airless sprayer models.
The siphon tube creates the essential fluid pathway from the material container to the sprayer pump, enabling consistent material pickup and flow. A properly functioning tube ensures efficient suction, prevents air ingestion into the system, and maintains reliable sprayer operation. Damage or restriction in this component can lead to poor material pickup, inconsistent spraying, or pump performance issues.
