Titan 0551681 Fluid Section Housing or Pump Manifold
OEM Titan Pump Component
Titan 0551681 Fluid Section Housing is the central component of the pumping system in compatible Titan and SprayTECH sprayers. This precision-machined pump manifold contains the internal fluid passages, valve chambers, and cylinder bore that channel material from the inlet through the pumping chamber and out to the spray gun.
Compatibility Overview
Replacing a worn or damaged fluid section housing restores proper fluid flow, pressure integrity, and pump reliability.

Titan 0551681 Fluid Section Housing or Pump Manifold
Titan 0551681 is an OEM fluid section housing, also known as a pump manifold, that forms the structural and functional core of the pumping system in compatible Titan and SprayTECH airless sprayers. This precision-machined component contains the internal fluid passages, inlet and outlet valve chambers, and the cylinder bore where the piston reciprocates. It is listed in official Titan parts diagrams for the EPX2355 Fluid Section Assembly and the Advantage 600 Pump Manifold.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan/SprayTECH 0551681 fluid section housing / pump manifold. Listed in the official EPX2355 Fluid Section Assembly (P/N 0551675) as item 4 and in the Advantage 600 manual as "Pump manifold (includes item 22)." |
| Function | Provides the structural foundation for the entire fluid section. Contains internal fluid passages that channel material from the inlet valve, through the pumping chamber, and out to the outlet valve. Houses the cylinder bore where the piston reciprocates. Withstands high operating pressures and resists corrosive paints and solvents. |
| Compatible Titan Models | Advantage 600 (Upright), Advantage GPX 85, PowrLiner 2850 GB_D_F, PowrLiner 1800M, PowrLiner 2800M. Verify fitment against your specific model parts diagram before ordering. |
| Compatible SprayTECH Models | Airless Advantage EPX2355, Airless EPX2355, GPX 85. Verify fitment against your specific model parts diagram. |
| Common Failure Symptoms | External fluid leaks from housing cracks. Loss of pressure or inability to build pressure. Visible cracks, corrosion, or wear on the housing body. Internal contamination where debris or paint appears in unexpected areas. |
| Service Guidance | When replacing the housing, transfer all internal components such as valves and seals from the old housing. Always use new seals and gaskets during reassembly. Inspect the piston rod, inlet and outlet valves, and all packings for wear to ensure a complete and reliable repair. |
| Related Parts Serviced Together | Piston rod / piston (check for wear), inlet and outlet valves (seat in housing, replace if worn), seals and packings (always replace when servicing housing), and fluid section bolts. |
| Commercial Benefits | Restores pump pressure integrity, eliminates fluid leaks, ensures proper internal passage alignment, and extends the service life of the entire fluid section. |
The 0551681 Fluid Section Housing is a critical replacement for contractors and service technicians maintaining compatible Titan and SprayTECH sprayers. If the pump cannot build or maintain pressure, fluid leaks from the housing body, or visible cracks or corrosion are present, the housing may need replacement. This component is the foundation of the pumping system, and a compromised housing can cause internal leaks, pressure loss, and contamination of other pump components. When replacing the housing, transfer all internal valves and seals, use new gaskets throughout, and inspect the piston rod and packings for wear. Replacing a worn housing promptly restores pump integrity and reliable spray performance.
