Helix part 0138404 is a spring used in the pump or valve assembly of compatible sprayers. This precision spring provides the necessary force to return components to their resting position, maintain pressure on seals, or assist in valve actuation. A weakened, broken, or corroded spring can cause improper valve operation, pressure loss, or erratic pump performance. Replacing with this genuine Helix spring restores proper mechanical function and reliable operation on the Helix LP.

The 0138404 Spring is a precision-engineered component used in the pump or valve assembly of the Helix LP sprayer. It provides consistent mechanical force to return pistons, valves, or other moving components to their correct positions during operation.
Springs play a critical role in maintaining proper valve sealing, ensuring check valves close correctly, and assisting in the smooth operation of mechanical components. Over time, springs can weaken due to metal fatigue, corrode from material exposure, or break under stress. A compromised spring can lead to valve leakage, pressure loss, erratic pump behavior, or complete component failure. Replacing a worn or broken spring with this genuine Helix part restores proper mechanical function and reliable operation.
| Return force | Returns pistons or valves to resting position after each stroke |
|---|---|
| Valve sealing | Maintains pressure on check valves for proper closure |
| Component actuation | Assists in moving mechanical parts during operation |
| Dampening | Absorbs shock and reduces wear on moving components |
| Broken spring | Visible fracture or separation |
|---|---|
| Weakened tension | Spring no longer provides adequate force (shorter free length) |
| Corrosion damage | Rust or pitting that weakens the spring |
| Valve leakage | Check valves fail to close properly due to insufficient spring pressure |
Helix part 0138404 is compatible with the following Helix sprayer model. Always confirm fitment using the correct parts diagram for your exact model and revision.
| Helix Model | Component |
|---|---|
| Helix LP | Spring |
| Helix LP (all variants) | Spring |
When replacing the spring, consider inspecting or replacing these associated components to ensure complete system restoration.
Inspect for wear; spring works with these components for proper sealing.
Check for wear if spring is part of the piston return mechanism.
May include seals, packings, and o-rings for comprehensive pump service.
