Hydrax part 2402315A is a Siphon Tube Assembly designed for the Hydrax 4540-7230. This assembly draws coating material from the container to the pump, featuring a screened inlet to filter debris and a weighted pickup for proper submersion. Replacing a cracked, collapsed, or clogged siphon tube assembly restores proper fluid flow and prevents pump cavitation.

The Hydrax 2402315A Siphon Tube Assembly is a complete replacement pickup tube system for the Hydrax 4540-7230. It connects the pump inlet to the material container, providing a flexible yet kink‑resistant path for fluid delivery.
This assembly typically includes a reinforced hose that resists collapse under vacuum, a weighted or rigid pickup tube end with a screened inlet to filter debris, and appropriate fittings for secure attachment. A properly functioning siphon tube is critical for consistent pump priming and steady material flow. Over time, tubes can develop cracks, become clogged with dried paint, or suffer from collapsed walls that restrict flow. Replacing a worn or damaged siphon tube assembly restores reliable priming and prevents pump cavitation.
| Fluid pickup | Draws paint or coating from container to pump inlet |
|---|---|
| Debris filtration | Integrated screen prevents large particles from entering pump |
| Kink resistance | Reinforced construction prevents collapse under suction |
| Cracks / leaks | Visible cracks or splits in tube wall |
|---|---|
| Collapsed section | Tube flattens or restricts flow under suction |
| Clogged screen | Inlet screen is blocked and cannot be cleaned effectively |
| Poor priming | Pump struggles to draw fluid or loses prime |
Hydrax part 2402315A is compatible with the following Hydrax model. Always confirm fitment using the correct parts diagram for your exact model and revision.

When replacing the siphon tube assembly, these components are often inspected or replaced at the same time to ensure complete inlet system reliability.
The pump inlet screen may also be clogged; clean or replace as needed.
Inspect clamps for corrosion or loss of tension; replace if necessary.
If debris passed through a damaged screen, inspect inlet valve for wear.
