Titan 0551437 Siphon Tube Assembly

Siphon tube assembly 0551437 for airless sprayers

The 0551437 siphon tube assembly is a fluid intake component that connects the sprayer pump to the material container. It is designed for use with SprayTech Airless EPX2355, EPX2255, EPX2155, SprayTech Airless Advantage EPX2155, and RentSpray 400 models. This assembly provides a dedicated path for coating to travel from the container to the pump inlet. Over time, siphon tubes can become cracked, brittle from chemical exposure, or clogged with dried material. A damaged tube allows air to be drawn into the system, leading to spitting at the gun, pressure fluctuations, and reduced efficiency. The tube length and diameter are matched to the pump's flow requirements to ensure proper prime and consistent material delivery. Replacing a worn or incorrect tube restores the sprayer's ability to draw fluid effectively, especially with thicker coatings. The assembly typically includes the pickup tube and may incorporate a filter or weight to keep the end submerged. When installing, ensure the tube is securely attached and that the end remains immersed during operation to prevent air ingestion. Regular inspection of the siphon tube for signs of wear or damage is recommended as part of routine sprayer maintenance. Using the correct replacement part maintains the original performance and helps avoid downtime on the job site.
