Titan 800-903 Return Hose and 9984595 Hose Assembly
Titan 800-903 is an OEM return hose that replaces Titan 507964, used in the fluid recirculation circuit of compatible airless sprayers. It returns excess paint from the pressure control valve or gun back to the container during priming or pressure relief, helping maintain stable pressure and prevent pump overheating. Titan 9984595 is a 25-foot bonded hose assembly for Titan AirCoat air-assisted airless systems. This bonded configuration combines material and air lines into a single streamlined unit, improving maneuverability and reducing hose entanglement during operation.
| Detail | Technical / Commercial Information |
|---|---|
| Return Hose Overview | OEM Titan 800-903 return hose, direct replacement for Titan 507964. Flexible, chemical-resistant hose used in the fluid recirculation circuit. Returns excess paint from the pressure control valve or gun to the container during priming or pressure relief. |
| Return Hose Function | Recirculates paint during priming and pressure relief. Maintains pressure stability by preventing spikes. Provides a path for depressurizing the system. Reduces stress on the pump by allowing material to bypass when the gun is not triggering. |
| Return Hose Compatible Models | Impact 1140, 1140 I, 1140 IA, 840, 840 I, 840 IA, 740/840, 1040; Advantage 1100, 700; Airless Sprayer 1140IX, 1140I, 840I, 840IX. Verify fitment against your specific model parts diagram. |
| Return Hose Failure Symptoms | Visible cracks or paint weeping from the hose. Hose hardening or brittleness. Clogs from dried paint preventing recirculation. Erratic pressure or inability to relieve pressure. Difficulty priming. |
| Hose Assembly Overview | OEM Titan 9984595 bonded hose assembly for AirCoat air-assisted airless systems. 25-foot (7.5 m) bonded configuration combining material and air lines. Material: DN3, 27 MPa (270 bar, 3916 psi). Air: DN6, 0.8 MPa (8 bar, 116 psi). |
| Hose Assembly Features | Bonded design integrates air and fluid hoses into one unit. Improves maneuverability and reduces entanglement. Durable construction for professional use. Maintains synchronized air and fluid delivery required for air-assisted airless spraying. |
| Related Parts Serviced Together | For return hose: pressure control valve, siphon tube, hose clamps. For hose assembly: gun swivel, fluid filter, air regulator, and AirCoat spray gun components. |
| Commercial Benefits | Genuine OEM hoses restore proper fluid recirculation and synchronized air/fluid delivery, ensuring consistent pressure, reliable priming, and optimal spray performance for professional applications. |
The 800-903 Return Hose and 9984595 Hose Assembly are practical service components for contractors maintaining compatible Titan sprayers. If the return hose is cracked, leaking, hardened, or clogged, recirculation and pressure relief will be impaired, leading to priming difficulties and pressure instability. For the bonded hose assembly, if the air or fluid lines are damaged, kinked, or no longer deliver synchronized flow, replacement restores proper AirCoat operation. Always relieve system pressure before servicing hoses, inspect fittings for damage, and verify the correct configuration for your specific model.
