## Summary description

Replacement hardened steel nozzle set designed for Elegoo Neptune 4 and Neptune 4 Pro 3D printers. The kit contains three 0.4 mm nozzles, one 0.6 mm nozzle and one 0.8 mm nozzle, providing options for fine-detail and faster, coarser extrusion. Hardened steel resists abrasive filaments and extends nozzle life for printing PLA, PETG, and composite materials.

## Long description

Hardened steel nozzle set for Elegoo Neptune 4 and Neptune 4 Pro printers, offering three 0.4 mm nozzles, one 0.6 mm nozzle and one 0.8 mm nozzle. The set provides options for high-detail printing with 0.4 mm and for faster, coarser extrusion with larger diameters. Hardened steel construction improves resistance to abrasive filaments and increases nozzle lifespan for prolonged use.
Advantages
The hardened steel nozzles resist wear from composite and abrasive filaments, so they last longer than standard brass nozzles. Multiple diameters in one kit let you switch between fine-detail prints and faster, large-layer prints without needing separate purchases. Included accessories simplify installation and routine maintenance, helping to keep your Neptune 4 / 4 Pro running reliably.
Suitable for
Fine-detail parts and models using 0.4 mm nozzles
Larger, faster prints and prototypes using 0.6 mm or 0.8 mm nozzles
Printing with abrasive or composite filaments (e.g., filled PLA, PETG blends)
Users who want spare nozzles and maintenance tools for Neptune 4 / 4 Pro
When it may not be suitable
This nozzle set is designed specifically for Elegoo Neptune 4 and Neptune 4 Pro hotend fittings; it may not fit other printer models without compatible hotend geometry. If you only print non-abrasive filaments and prefer maximum thermal conductivity for very high-speed printing, a brass nozzle could be preferable due to its higher thermal conductivity compared with hardened steel.
Key specifications
Material: hardened steel
Nozzle diameters: 0.4 mm ×3, 0.6 mm ×1, 0.8 mm ×1
Included accessories: two cleaning needles, one wrench, one storage container
Compatibility: Elegoo Neptune 4 and Neptune 4 Pro
How to use
Select the nozzle diameter that matches your desired layer height and print speed, then power off the printer and heat the hotend to a recommended temperature for safe removal. Use the supplied wrench to unscrew the installed nozzle once the hotend is heated and wear heat-resistant gloves if required. Screw in the chosen hardened steel nozzle, tighten securely but avoid overtightening, and perform a test extrusion and calibration before starting production prints.
What to consider before purchase
Ensure your printer is an Elegoo Neptune 4 or Neptune 4 Pro or has a compatible hotend thread and geometry
Hardened steel has lower thermal conductivity than brass; this can affect heating and cooldown behavior
Consider required nozzle diameter for desired print detail and speed
Usage recommendations
Use 0.4 mm nozzles for detailed models and small features; choose 0.6 mm or 0.8 mm for faster prints and larger layer heights. Clean nozzles regularly with the supplied needles and perform retraction and temperature tuning after a nozzle change to maintain print quality.
