0295575 Needle Spring is a precision component used in the fluid control assembly of compatible HVLP sprayers. This spring provides the necessary tension to return the fluid needle to the closed position when the trigger is released, ensuring positive shut-off and preventing material drip. A properly functioning needle spring maintains consistent material flow control and reliable trigger response. This spring restores correct needle seating and fluid shut-off performance on compatible SprayTech units.

The 0295575 Needle Spring is a critical component within the fluid control assembly of the SprayTech HVLP Maxum II sprayer. This spring works in conjunction with the fluid needle to create a reliable sealing mechanism. When the trigger is pulled, the needle retracts against spring tension to allow material flow through the fluid tip. Releasing the trigger allows the spring to return the needle to its seated position, stopping material flow instantly. This action prevents drips, sags, and material waste between spray passes. The spring also maintains consistent tension that influences trigger feel and the responsiveness of fluid delivery throughout the spray pattern.
Over time, the needle spring can weaken from repeated compression cycles or become corroded from exposure to solvents and coatings. A compromised spring may not provide sufficient force to fully seat the needle, leading to weeping from the tip, inconsistent material flow, or failure to achieve complete shut-off. Replacing the spring restores proper needle seating, eliminates unwanted dripping, and returns consistent fluid control characteristics. This spring is manufactured to original specifications to ensure correct tension and compatibility with the HVLP Maxum II fluid section assembly.
| Positive shut-off | Returns the fluid needle to the seated position when trigger is released |
|---|---|
| Drip prevention | Eliminates material weeping from the tip between spray passes |
| Consistent flow control | Maintains proper tension for predictable fluid delivery and trigger response |
| Tip dripping | Material continues to flow or drip after trigger is released |
|---|---|
| Weak spring tension | Trigger feels loose or needle does not return quickly after release |
| Corrosion or damage | Visible rust, pitting, or deformation on the spring coils |
| Inconsistent flow | Fluctuating material delivery that affects spray pattern quality |
The 0295575 Needle Spring is compatible with the following SprayTech sprayer. Always confirm fitment using the correct parts diagram for your exact model and revision.

Fluid control issues often involve multiple components in the fluid section. When servicing the needle spring, these parts are commonly inspected or replaced at the same time.
A worn or scored needle will not seat properly even with a new spring, causing continued dripping.
Damage to the fluid tip seat prevents complete shut-off regardless of spring condition.
Worn packing can allow material leakage along the needle shaft and affect spring performance.
