Titan 0533590 Siphon Tube

Titan 0533590 Siphon Tube

Sourced From:
Titan Tools Inc.

 

Titan part 0533590 is a siphon tube used to draw material from the supply container into the pump on the AirCoat 423 spray system. When the original siphon tube becomes cracked, clogged, or damaged, it can cause cavitation, loss of prime, and inconsistent spray performance. This tube restores proper material intake and reliable pump operation.

Siphon Tube for AirCoat 423 Spray System

The Titan part 0533590 Siphon Tube is a fluid intake component designed specifically for the AirCoat 423 spray system. This tube extends into the material container and draws coating material up to the pump, ensuring a steady, reliable supply for consistent spray performance in professional finishing applications.

A damaged or compromised siphon tube can lead to air ingestion, loss of prime, cavitation, and pressure fluctuations. Replacing with this genuine component ensures proper material intake, reliable priming, and consistent operation of your AirCoat 423 system.

Fluid Intake Insight: The siphon tube works in conjunction with the suction strainer. Regular inspection of both components is essential—a cracked tube or clogged strainer are common causes of pump performance issues that are often overlooked.

What it does and when to replace it

What the siphon tube does
Material intake Draws coating material from container to pump
Prime maintenance Maintains continuous fluid column for pump prime
Air prevention Proper seal prevents air from entering system
Flow delivery Ensures consistent material supply to pump
When replacement is recommended
Cracks or damage Visible cracks causing air leaks or fluid drip
Loss of prime Pump repeatedly loses prime during operation
Air bubbles Visible air in fluid line indicating tube leak
Brittleness Tube hardened or brittle with age

Frequently Asked Questions

A damaged siphon tube can cause several performance issues: air leaks introduce bubbles into the fluid stream, causing sputtering and inconsistent pressure; cracks can lead to loss of prime, requiring repeated priming; restricted flow reduces maximum output; and debris entering through cracks can damage pump packings and valves. Many intermittent performance problems trace back to the siphon tube—it's often overlooked during diagnosis.

Repairing a cracked siphon tube with tape or sealants is not recommended. Such repairs are temporary and often fail under the vacuum created during pump operation, leading to air ingestion. The tube is also exposed to various solvents and materials that can deteriorate repair materials. Replacement with the genuine 0533590 siphon tube ensures reliable sealing and long-term performance.

The 0533590 siphon tube is manufactured from material specifically selected for compatibility with the solvents and coatings used in AirCoat finishing systems. It is typically made from a durable, chemical-resistant material that maintains flexibility over time while resisting degradation from paints, thinners, and cleaning solvents commonly used in professional finishing applications.

Installation typically involves: 1) Removing the old tube and cleaning the pump inlet fitting, 2) Attaching the suction strainer to the tube end if separate, 3) Inserting the tube into the pump inlet, ensuring it seats fully, 4) Securing with any provided clamps or fittings, and 5) Positioning the tube so the end rests near the bottom of the material container without blocking flow. Test prime before operation to verify proper sealing.
