Titan 2366643A Siphon Tube

Part number 2366643A is a Siphon Tube, a precision-formed rigid pickup assembly specifically engineered for the Titan Elite 3500 and Elite 3500 72v airless sprayer systems. This vertical tube extends from the pump inlet downward into the material container, providing the critical fluid pathway through which coating material is drawn into the pumping mechanism. The siphon tube works in conjunction with the integral filter screen to prevent debris from entering the pump while maintaining uninterrupted material flow during continuous spraying operations.

Constructed from corrosion-resistant materials, this siphon tube is engineered to withstand the chemical attack of solvents, water-based coatings, and abrasive pigments encountered in professional painting applications. The rigid design maintains consistent positioning within the material container, preventing the tube from floating, shifting, or drawing air from the surface. The precisely calibrated length ensures complete material utilization while preventing the pickup of settled solids from the container bottom. The upper end features precision-formed threads or press-fit geometry that creates a secure, leak-proof connection to the pump inlet manifold.

Siphon tubes are subjected to mechanical stress during container changes, cleaning, and transport. Failure modes include bending or kinking from impact, cracks at the mounting interface from over-tightening, clogging of the inlet screen from inadequate filtration, and chemical degradation of the tube material. A damaged, bent, or clogged siphon tube causes difficult priming, intermittent material supply leading to spitting or surging spray patterns, and incomplete material utilization. Replacement with a genuine 2366643A siphon tube restores reliable priming and consistent fluid delivery.
