Titan part 704-397A is a return hose assembly designed to transport unused coating material from the spray gun or manifold back to the pump or hopper on compatible PowrLiner 1800M and 2800M stripers. This assembly includes the hose and pre‑attached fittings for a direct, leak‑free replacement. Replacing a cracked, kinked, or worn return hose restores proper recirculation flow, prevents pressure drops, and eliminates hazardous leaks during operation.

The Titan 704-397A Return Hose Assembly is an OEM replacement hose used to recirculate excess coating material from the spray gun or manifold back to the pump inlet or material hopper on PowrLiner 1800M and 2800M line stripers. It is constructed from solvent‑resistant material and comes with pre‑installed fittings for a quick, drop‑in installation.
Return hoses are exposed to continuous flexing, abrasion, and harsh chemicals. Over time, they can develop cracks, kinks, soft spots, or fitting leaks. A damaged return hose causes material spray, pressure loss, and potential safety hazards. Replacing with genuine Titan 704-397A restores leak‑free recirculation, maintains proper system pressure, and ensures a clean, safe work environment.
| Material recirculation | Returns unused coating to pump or hopper |
|---|---|
| Pressure maintenance | Helps stabilize system pressure |
| Leak prevention | Contains material within closed loop |
| Cracks or cuts | Visible damage to hose outer cover |
|---|---|
| Kinking | Hose stays bent, restricting flow |
| Fitting leaks | Material seeps from swivel or crimp |
| Bulging or soft spots | Internal reinforcement failure |
Titan part 704-397A is compatible with the following striper models. Always confirm fitment using the correct parts diagram for your exact machine and serial number.

When replacing the return hose assembly, consider inspecting or replacing these related components.
Inspect the high‑pressure supply hose for wear; replace if both hoses show similar age or damage.
Check for corrosion or thread damage; replace if the new hose does not seal properly.
Ensure the return port on the pump or manifold is clean and free of obstructions.
