Titan part 341241 is a knocker for the inlet valve used in the fluid section of PowrLiner 5500 and Elite 5500 airless sprayers. This component helps dislodge debris and ensure proper seating of the inlet valve ball or poppet, improving pump priming and consistent material flow. Replace a worn, deformed, or missing knocker to restore reliable inlet valve operation, prevent pressure loss, and reduce valve sticking.

The Titan 341241 Knocker For Inlet Valve is a small but critical component inside the fluid section of PowrLiner 5500 and Elite 5500 airless sprayers. It is positioned near the inlet valve ball or poppet and creates a mechanical impact each time the piston cycles, helping to dislodge debris, break up dried paint, and ensure the valve seats fully. This action improves priming, prevents valve sticking, and maintains consistent material flow.
Over time, the knocker can wear, deform, or become damaged by abrasive materials or corrosion. A missing or worn knocker can cause the inlet valve to stick open or closed, resulting in poor priming, pressure loss, erratic spray, or complete pump failure. Replacing a damaged knocker with a genuine Titan 341241 restores proper valve operation, improves pump efficiency, and extends fluid section life.
| Prevents valve sticking | Knocks debris off the inlet valve ball/poppet each cycle |
|---|---|
| Improves priming | Helps valve seat properly for consistent suction |
| Extends valve life | Reduces wear by keeping sealing surfaces clean |
| Visible wear or damage | Flat spots, cracks, deformation, or corrosion |
|---|---|
| Poor priming | Sprayer runs but won't draw paint or loses prime |
| Erratic pressure | Pressure fluctuates or drops unexpectedly |
| Rebuilding fluid section | Always replace knocker when replacing inlet valve components |
Titan part 341241 is compatible with the following airless sprayers. Always confirm fitment using the correct parts diagram for your exact model.
| Brand / Model | Component |
|---|---|
| PowrLiner 5500 | Knocker for inlet valve |
| Elite 5500 | Knocker for inlet valve |
When replacing the inlet valve knocker, inspect and replace these components as a set.
The seat wears together with the ball – replace both for a proper seal.
The knocker acts directly on the ball – replace if scored or out of round.
If inlet valve is worn, the outlet valve may also need replacement.
