| Part Description | Lower Packing |
| Brand | Titan |
| Fits | Impact 410, 400, 340 |
| Condition | New |
The 0532915 Lower Packing is a critical wear component in the fluid pump of Impact 410, 400, and 340 airless sprayers. It seals the lower end of the piston, preventing paint from leaking into the pump housing and ensuring consistent hydraulic pressure for a smooth, even spray pattern.
A worn or damaged lower packing can cause paint leakage from the pump, loss of pressure, erratic operation, or the sprayer failing to prime. Replacing the packing restores the seal, improves pump efficiency, and extends the service life of the piston and cylinder.
| Seals piston | Prevents paint from leaking past the piston during the pumping cycle |
|---|---|
| Maintains pressure | Ensures hydraulic pressure is delivered to the spray gun without loss |
| Protects pump | Keeps abrasive paint particles from damaging the pump housing and bearings |
| External leakage | Paint drips or sprays from the pump lower area |
|---|---|
| Loss of pressure | Pressure drops or surging even with new spray tip and proper fluid |
| Hard to prime | Pump struggles to build initial pressure or loses prime easily |
| Visible damage | Packing is cracked, hardened, or deformed when inspected |
Part 0532915 is compatible with the following Impact models. Always verify fitment using the correct parts diagram for your specific sprayer.
| Model | Component |
|---|---|
| Impact 410 | Lower Packing |
| Impact 400 | Lower Packing |
| Impact 340 | Lower Packing |
When replacing the lower packing, these components are often inspected or replaced to ensure a complete pump overhaul.
Inspect for scoring, nicks, or wear; replace if damaged.
Check for scratches or corrosion that could compromise the seal.
Consider replacing both upper and lower packings together for optimal performance.
