Product Information
Full details
The DeVilbiss SGK-0414 replacement fluid needle is an essential maintenance component designed for professional painters and hobbyists using the DeVilbiss FLG gravity spray gun series. Featuring a precise 1.4mm tapered shaft, this component restores consistent fluid delivery and atomization, ensuring high-quality finishes on automotive, furniture, or industrial projects. While this needle is engineered for a seamless fit, users must ensure their specific FLG model is compatible, as incorrect needle sizing can result in uneven spray patterns or potential damage to the fluid nozzle.

FAQs
Is this needle compatible with all DeVilbiss guns?
No, this needle (SGK-0414) is specifically engineered for the DeVilbiss FLG gravity spray gun series.
Do I need to replace the fluid nozzle when replacing the needle?
While not strictly required, it is best practice to inspect the fluid nozzle for wear. If the needle was bent, it may have damaged the internal seat of the nozzle.
How do I know if my needle is bent?
Remove the needle and roll it on a perfectly flat glass surface. If you see any wobble or inconsistent movement, the needle is bent and should be replaced.
Can I use this for waterborne paints?
Yes, the materials used in the SGK-0414 are compatible with modern solvent and waterborne paint systems, provided proper cleaning procedures are followed.
What is the primary function of the 1.4mm size?
The 1.4mm size is considered the 'all-purpose' setting, providing a balance between paint flow and atomization for most basecoats, clears, and primers.
Troubleshooting
Paint continues to flow after the trigger is released
Check if the needle is fully seated in the fluid nozzle or if there is debris obstructing the nozzle orifice.
Spray pattern is uneven or split
Verify that the needle is not bent and is properly centered within the fluid nozzle.
Needle is sticking during trigger movement
Loosen the needle packing nut slightly and ensure the needle shaft is clean and lubricated with a gun-safe lubricant.

Setup, Compatibility & Care
To install the needle, first depress the trigger and remove the old assembly by loosening the needle packing nut at the rear of the gun. Carefully slide the new SGK-0414 needle through the rear housing, ensuring it does not strike the fluid nozzle opening prematurely, which could cause damage. Once inserted, tighten the packing nut just enough to prevent leaks; overtightening will cause the needle to stick. For care, always flush the gun with an appropriate cleaning solvent immediately after use. Avoid using wire brushes or abrasive tools on the needle tip, as even minor scratches can permanently ruin the spray pattern.
