## Summary description

Replacement hardened steel nozzle set compatible with Elegoo Neptune 4 Plus and 4 Max. Includes three 0.4 mm nozzles, one 0.6 mm nozzle and one 0.8 mm nozzle for varied extrusion widths. Designed for wear resistance when printing abrasive or filled filaments, offering reliable flow and longer service life for desktop FDM printing.

## Long description

Hardened steel nozzle set for Elegoo Neptune 4 Plus and 4 Max including three 0.4 mm, one 0.6 mm and one 0.8 mm nozzle. The set is intended as a durable replacement for standard nozzles and provides options for fine detail and faster infill by changing extrusion width. Hardened steel construction improves wear resistance when printing abrasive or filled filaments and supports consistent filament flow for desktop FDM printing.
Advantages
Multiple nozzle diameters in one kit allow quick switching between detailed prints and larger, faster prints. Hardened steel increases resistance to abrasion from filled and composite filaments, extending nozzle life compared with standard brass nozzles. The kit also includes cleaning needles and a wrench, which simplify maintenance and nozzle replacement.
Suitable for
Users of Elegoo Neptune 4 Plus and Neptune 4 Max seeking durable replacement nozzles
Printing with abrasive or filled filaments (carbon, metal, glass filled)
Projects that require a mix of fine detail (0.4 mm) and faster, coarser infill (0.6–0.8 mm)
When it may not be suitable
This nozzle set is not necessary for users who only print standard PLA or other non-abrasive filaments and prefer the thermal conductivity of brass for slightly higher flow thermal transfer. If you require specialised nozzle geometries (for example volcano-style high-flow nozzles) or diameters outside the included sizes, this kit will not cover those needs.
Key specifications
Material: hardened steel
Nozzle diameters: 0.4 mm ×3, 0.6 mm ×1, 0.8 mm ×1
Compatibility: Elegoo Neptune 4 Plus, Elegoo Neptune 4 Max
Accessories included: two cleaning needles, one wrench, storage container
How to use
Power off and cool the hotend before changing nozzles. Use the supplied wrench to unscrew the fitted nozzle, remove any filament residue with the cleaning needles, then install the selected hardened steel nozzle and tighten to the manufacturer’s recommended torque. After replacement, recalibrate nozzle height and perform a test print to confirm extrusion and first-layer adhesion.
What to consider before purchase
Ensure mechanical compatibility with Elegoo Neptune 4 Plus / 4 Max hotend and mounting thread
Consider filament types you use—hardened steel is best for abrasive/filled materials
Note that thermal conductivity differs from brass; printing temperatures or retraction settings may need adjustment
Usage recommendations
For best results, use the 0.4 mm nozzles for detailed parts and the 0.6–0.8 mm nozzles for faster infill or stronger perimeters. Clean nozzles regularly when switching abrasive filaments and re-level the bed after nozzle changes.
