702-239 is a bypass hose used in the fluid recirculation system of compatible airless sprayers. This hose redirects excess fluid back to the pump inlet or container to regulate pressure, prevent overheating, and maintain consistent spray performance. Replace a worn, cracked, or leaking bypass hose to ensure proper system operation and prevent pressure fluctuations.

The 702-239 bypass hose is an OEM replacement component used in the fluid recirculation system of compatible airless sprayers. It carries excess fluid from the pump outlet back to the pump inlet or container, helping to regulate pressure, reduce pump strain, and prevent overheating during operation.
Over time, bypass hoses can become cracked, kinked, or abraded due to exposure to chemicals, heat, and vibration. A damaged bypass hose can lead to pressure loss, erratic spray patterns, or fluid leaks. Replacing it with this genuine hose restores proper system function and ensures reliable performance.
| Pressure regulation | Recirculates excess fluid to maintain stable pressure |
|---|---|
| Pump protection | Reduces strain and prevents overheating |
| System stability | Ensures consistent fluid flow and spray quality |
| Leaks / ruptures | Fluid escaping from hose or fittings |
|---|---|
| Kinks / crimps | Restricted flow causing pressure issues |
| Cracks / abrasion | Visible damage to hose outer layer |
| Pressure fluctuations | Inconsistent spray performance traced to bypass circuit |

When replacing the bypass hose, inspect these associated components to ensure complete system reliability.
The valve controls flow through the bypass; check for proper operation.
Inspect fittings for leaks, corrosion, or thread damage.
A clogged filter can increase bypass demand; clean or replace as needed.
