## Summary description

Replacement brass nozzle set designed for Elegoo Neptune 4 and Neptune 4 Pro FDM 3D printers. The kit includes two 0.2 mm nozzles, four 0.4 mm nozzles, two 0.6 mm nozzles and two 0.8 mm nozzles, allowing control over layer detail and extrusion flow for different filament types and print speeds. Suitable for nozzle upgrades, maintenance and multi-resolution printing.

## Long description

Brass nozzle set for Elegoo Neptune 4 and Neptune 4 Pro FDM printers includes ten nozzles in four diameters: two 0.2 mm, four 0.4 mm, two 0.6 mm and two 0.8 mm. The kit is intended as a replacement or upgrade set to change extrusion width and layer detail according to the needs of a specific project. The package also contains basic maintenance tools to help prevent and resolve filament flow issues during printing.
Advantages
Brass construction offers good thermal conductivity and smooth filament flow for standard filaments. Multiple nozzle sizes in one kit let you switch between fine-detail printing and faster, coarser extrusion without needing separate orders. Included cleaning needles and a wrench simplify nozzle swaps and routine maintenance.
Suitable for
Fine-detail models and miniatures (use 0.2 mm nozzles)
General-purpose printing and most filaments (use 0.4 mm nozzles)
Larger parts and faster prototyping (use 0.6 mm or 0.8 mm nozzles)
Maintenance, replacement and testing different layer heights
When it may not be suitable
This brass nozzle set is not ideal for abrasive filaments such as carbon-fiber, glow-in-the-dark or metal-filled blends because brass wears faster with abrasive additives. For high-abrasion materials, a hardened steel or coated nozzle is more appropriate. Also, extremely high-temperature filaments may require nozzle materials rated for higher temperatures.
Key specifications
Compatible printers: Elegoo Neptune 4 and Neptune 4 Pro
Material: brass
Nozzle diameters: 0.2 mm ×2, 0.4 mm ×4, 0.6 mm ×2, 0.8 mm ×2
Contents: cleaning needles, wrench, storage tube/container
How to use
Select a nozzle diameter that matches the desired layer height and print speed, power off the printer and heat the hotend to a low working temperature to ease removal of the existing nozzle. Use the supplied wrench to unscrew the old nozzle, install the replacement nozzle and tighten securely while the hotend is warm but stable. After installation, recalibrate bed leveling and adjust slicer settings (nozzle diameter, layer height, print speed, extrusion multiplier) before printing.
What to consider before purchase
Whether you print abrasive filaments (if yes, consider hardened or coated nozzles)
Required nozzle diameters for your typical projects (detail vs speed)
Compatibility with Elegoo Neptune 4 / 4 Pro hotend design
Usage recommendations
For detailed models choose the 0.2 mm nozzles and reduce layer height and print speed. For large parts or faster output use 0.6–0.8 mm nozzles and increase extrusion width and layer height. Clean nozzles regularly with the supplied needles and perform a short test print after each swap to fine-tune extrusion settings.
