Part number 0276244 is a needle and stop assembly. This critical component controls the flow of material through the spray gun by opening and closing the fluid nozzle. It is compatible with the Spraytech HVLP Maxum II spray gun. The needle moves in and out of the nozzle seat via the trigger, while the adjustable stop determines the maximum needle retraction for precise fan pattern control.

Part number 0276244 is a needle and stop assembly. This assembly is the core mechanical component responsible for regulating material flow in an HVLP spray gun. The precision-ground needle seats against the fluid nozzle to stop flow and retracts to allow material to spray.
This assembly is compatible with the Spraytech HVLP Maxum II spray gun. A worn, bent, or damaged needle can cause leaks, poor atomization, or an inability to shut off material flow. The adjustable stop allows the user to set the maximum fan width. Replacing this assembly restores precise fluid control and spray pattern performance.
| Flow Control | The needle opens and closes the fluid passage to start/stop spray. |
|---|---|
| Pattern Adjustment | The stop screw limits needle retraction to control fan width. |
| Sealing | Needle tip seals against the nozzle seat to prevent drips when closed. |
| Trigger Linkage | Translates trigger movement into precise linear needle motion. |
| Fluid Leak/Drip | Material drips from nozzle when gun is not triggered. |
|---|---|
| Poor Atomization | Spray pattern is splattered or uneven due to a worn needle tip. |
| Incomplete Shut-off | Material continues to flow even when trigger is fully released. |
| Sticky Trigger | Needle binds in guide due to damage or dried material. |
The needle and stop assembly part 0276244 is designed specifically for the following spray gun model.
| Compatible Spray Gun Model | Component |
|---|---|
| Spraytech HVLP Maxum II | Needle/Stop Assy |
For optimal spray gun performance, these components are often inspected or replaced at the same time as the needle assembly.
The seat against which the needle seals. It is often worn in tandem with the needle.
The seal around the needle shaft that prevents material from leaking back into the gun body.
The mechanism that actuates the needle and returns it to the closed position.
