Titan part 704-116 is a Bypass Tube used in the fluid system of compatible airless sprayers. This rigid tube, often made of metal or durable plastic, creates a fixed internal passage for paint to recirculate within the pump or manifold assembly. It is a standard component for managing fluid flow and pressure in the sprayer's bypass circuit.

The Titan 704-116 is a genuine OEM Bypass Tube for the Titan 330 model airless sprayer. This part is a rigid, often straight or slightly curved tube that is installed within the pump housing or fluid manifold. It provides a dedicated internal passage for fluid to flow during the sprayer's bypass mode, allowing paint to recirculate safely when the gun is not triggered.
A cracked, clogged, or damaged bypass tube can disrupt the sprayer's internal fluid circuit. This can lead to improper bypass function, difficulty relieving system pressure, or internal fluid leaks that compromise performance. Replacing a faulty tube with the correct Titan 704-116 part restores the proper internal fluid pathway, ensuring reliable pressure management and system operation.
| Internal Bypass Passage | Creates a fixed, internal channel within a casting for fluid to bypass from a high-pressure zone back to a low-pressure area or the fluid inlet. |
|---|---|
| Pressure Relief | Helps the pressure relief valve function by providing a route for fluid to escape when pressure exceeds the set limit. |
| Component Integration | Often connects internal galleries within a pump block or manifold, replacing the need for an external hose in tight spaces. |
| Physical Damage | The tube is cracked, has a hole, is corroded through, or the ends are deformed. |
|---|---|
| Clogging | The internal bore of the tube is obstructed with dried paint or debris that cannot be cleared. |
| Pump or Manifold Overhaul | Replacing the tube as a standard part during a complete disassembly and rebuild of the fluid section. |
| Bypass System Failure | Diagnosis points to a failure in the internal bypass circuit, and the tube is a suspect component. |
The Titan 704-116 Bypass Tube is a model-specific part designed for a popular professional sprayer.
