SprayTech part 0276453 is a needle assembly #3 designed to control fluid flow through the spray gun on the SprayTech HVLP Maxum II sprayer. This precision component works in conjunction with the fluid nozzle to start and stop material flow with each trigger pull. Replacing a worn, bent, or damaged needle assembly restores proper spray control and ensures consistent, high-quality finish application.

The 0276453 Needle Assembly #3 is a precision component that controls fluid flow through the spray gun on the SprayTech HVLP Maxum II. This #3 size needle is engineered to work with corresponding fluid nozzles to provide the correct material delivery for various coating applications.
The needle assembly is the heart of the spray gun's fluid control system. When the trigger is pulled, the needle retracts from the fluid nozzle, allowing material to flow through and be atomized by the air cap. Releasing the trigger allows the needle to seat back into the nozzle, creating a positive shut-off that stops material flow instantly. The precision-ground tip must form a perfect seal with the nozzle seat to prevent drips and ensure clean start/stop performance.
Over time, needle tips can become worn, bent, or nicked, compromising the seal with the nozzle. A worn needle can cause inconsistent spray patterns, dripping when the gun is triggered off, or difficulty achieving proper atomization. Replacing the needle assembly restores precise fluid control, ensuring consistent, high-quality finishes and reducing material waste.
| Flow control | Starts and stops material flow by seating in the fluid nozzle |
|---|---|
| Atomization aid | Works with nozzle to create proper material breakup |
| Positive shut-off | Prevents dripping when gun is not triggered |
| Inconsistent spray pattern | Fluctuations in material delivery during spraying |
|---|---|
| Dripping / leaking | Gun continues to drip when trigger is released |
| Visible wear | Tip is bent, nicked, or worn |
| Poor atomization | Material not breaking up properly |

When replacing the needle assembly, these associated components are often inspected or replaced at the same time.
The mating component that the needle seats against; inspect for wear and replace if necessary.
Directs atomizing air; clean and inspect for damage.
Prevents fluid from leaking back through the gun body; replace if worn.
