## Summary description

Replacement 0.4 mm nozzle for Elegoo Neptune 4 and Neptune 4 Pro 3D printers, manufactured from hardened steel for improved wear resistance. Designed for 1.75 mm filament, it provides standard-diameter extrusion suitable for general-purpose printing, including PLA, PETG and abrasive blends where steel nozzles reduce wear. Fits Neptune 4 series hotends and supports straightforward installation.

## Long description

Nozzle 0.4 mm for 3D printers Elegoo Neptune 4/4 Pro is a hardened steel extrusion tip designed for use with 1.75 mm filament. It is a direct-replacement nozzle for the Neptune 4 series hotends and provides a standard 0.4 mm orifice for general-purpose printing. Manufactured from hardened steel, the nozzle resists abrasive wear better than brass alternatives while keeping dimensional stability needed for consistent extrusion of PLA, PETG and abrasive blends.
Advantages
The hardened steel construction improves longevity when printing with abrasive or composite filaments, reducing the frequency of nozzle replacement. A 0.4 mm diameter balances print speed and detail, delivering reliable layer lines for everyday printing tasks. The part is compatible with the Neptune 4 and Neptune 4 Pro hotends and supports straightforward installation using standard nozzle-change procedures.
Suitable for
 General-purpose 3D printing with PLA and PETG
 Printing abrasive or composite filaments that accelerate wear on brass nozzles
 Users of Elegoo Neptune 4 and Neptune 4 Pro printers requiring a durable replacement nozzle
 Prototyping and small-series production where nozzle durability is important
Key specifications
 Nozzle diameter: 0.4 mm orifice for standard extrusion
 Filament diameter compatibility: 1.75 mm
 Material: hardened steel for increased abrasion resistance
 Compatibility: designed to fit Neptune 4 series hotends (Neptune 4 / Neptune 4 Pro)
How to use
Before replacing the nozzle, heat the hotend to the operating temperature appropriate for the previously loaded filament to avoid clogging or filament breakage. Power off the printer after heating and use proper tools to remove the existing nozzle by holding the heater block steady and unscrewing the nozzle. Install the hardened steel nozzle by screwing it in until it seats against the heat break and then perform a final small turn at printing temperature to ensure correct sealing. After installation, recalibrate the first-layer height and perform a test print to verify extrusion and bed adhesion.
Usage recommendations
Use the hardened steel nozzle when printing abrasive filaments or when longer nozzle life is required. For optimal results with PLA and PETG, use standard print temperatures and re-level the bed after nozzle change. Avoid excessive tightening torque to prevent damage to the heater block threads.
