Part number 0276459 is a Needle #5 Assembly that includes a stainless steel guide. This assembly is a key component in the fluid control system of an HVLP spray gun. The needle moves forward and backward within the guide to open and close the fluid tip, regulating material flow. The stainless steel construction offers improved resistance to wear and corrosion compared to standard materials.
A worn, bent, or corroded needle assembly can cause fluid leaks, an uneven spray pattern, or a stiff trigger pull. Replacing the assembly restores precise fluid metering, reliable shut-off, and smooth trigger operation.
| Fluid Shut-off | Seals against the fluid tip to stop material flow when the trigger is released |
|---|---|
| Flow Control | Regulates the amount of material delivered by how far it is pulled back |
| Pattern Consistency | Works with the nozzle and air cap to create a uniform spray fan |
| Fluid Leakage | Paint drips from the fluid tip when the gun is not triggered |
|---|---|
| Trigger Problems | Stiff, sticky, or gritty feel when pulling the trigger |
| Pattern Defects | Uneven fan pattern, tails, or heavy material delivery on one side |
| Visible Damage | Bent needle, worn tip, corrosion, or scoring on the guide |
Part number 0276459 is designed for the SprayTech HVLP Maxum II spray gun. This needle assembly is matched to work with specific fluid tip sets. Always confirm fitment using the correct parts diagram for your exact model.

The needle, fluid tip, and air cap function as an integrated system. For optimal spray performance, these components are often inspected or replaced concurrently.
The needle seals against this tip. A worn or damaged tip will cause leaks even with a new needle.
These internal parts control needle movement and seal. Worn packing can cause leaks into the gun body.
The air cap atomizes the material. A clogged or damaged cap affects finish quality regardless of needle condition.
