SprayTech part 0551102 is a Suction Hose Assembly designed for SprayTech AirCoat Airless Sprayers. This hose draws coating material from the container to the pump, featuring a reinforced construction to prevent collapse under suction and a screened inlet to filter debris. Replacing a cracked, collapsed, or clogged suction hose restores proper fluid flow and prevents pump cavitation.

The SprayTech 0551102 Suction Hose Assembly is a complete replacement hose designed for the material intake system of SprayTech AirCoat Airless Sprayers. It connects the pump inlet to the paint 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 suction hose is critical for consistent pump priming and steady material flow. Over time, hoses can develop cracks, become clogged with dried paint, or suffer from collapsed walls that restrict flow. Replacing a worn or damaged suction hose restores reliable priming and prevents pump cavitation.

|---|---|
| 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 hose wall |
|---|---|
| Collapsed section | Hose 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 |

When replacing the suction hose 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.
