Part number 9885553 is a return tube fitting designed for Advantage Series GPX 33, PowrLiner 550, and SprayTech ED1150 airless sprayers. This fitting connects the return hose to the pump or fluid section, allowing excess paint to recirculate and maintain stable system pressure. A worn or cracked fitting can cause leaks, pressure loss, and priming difficulties. Replacing it restores proper fluid return and reliable operation.

The 9885553 return tube fitting is a precision component that connects the return hose to the pump or fluid section on compatible airless sprayers. It allows excess paint to recirculate back to the container or pump inlet, helping to maintain consistent pressure and prevent over-pressurization. This fitting is essential for proper system operation, especially during priming and bypass modes.
Manufactured from corrosion‑resistant materials, this fitting is designed to withstand the high pressures and chemical exposure common in airless painting. Over time, fittings can develop cracks, thread damage, or seal wear, leading to fluid leaks, pressure drops, and difficulty priming. Replacing a worn or damaged return tube fitting with genuine 9885553 restores system integrity and ensures reliable recirculation.
| Fluid return | Connects return hose to allow paint recirculation |
|---|---|
| Pressure regulation | Helps maintain stable system pressure during operation |
| Priming aid | Facilitates air removal during priming by redirecting flow |
| Fluid leakage | Paint seeping from the fitting threads or connection point |
|---|---|
| Visible cracks | Cracks in the fitting body |
| Damaged threads | Threads stripped or cross‑threaded, preventing secure connection |
| Priming issues | Difficulty priming due to air entering through a faulty fitting |

When replacing the return tube fitting, consider inspecting these associated components:
Check the hose for cracks, kinks, or brittleness; replace if worn.
The fitting may use an O‑ring; replace if flattened or hardened.
Debris in the inlet can cause return flow issues; inspect and clean.
