## Long description

Brass 0.4 mm replacement nozzle compatible with Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers. Designed for use with 1.75 mm filament, this metal nozzle offers a standard extrusion diameter suitable for everyday FDM printing tasks. The brass construction provides good thermal conductivity for consistent melt flow with common materials such as PLA and ABS, and it can be fitted quickly to restore printing precision or as part of routine maintenance.
Advantages
The brass 0.4 mm nozzle delivers a balance of print detail and extrusion speed, making it suitable for most general-purpose models. Its 1.75 mm filament compatibility matches widely used filament spools, and the metal body ensures stable thermal transfer during printing. The nozzle is a direct replacement designed to fit the specified Elegoo Neptune models, simplifying installation and reducing downtime.
Suitable for
General-purpose FDM printing with 1.75 mm filament
Prototyping and functional parts using PLA and ABS
Replacing worn or damaged nozzles to restore print quality
Routine maintenance and nozzle size changes for different layer heights
Key specifications
Nozzle diameter: 0.4 mm
Material: brass
Filament diameter supported: 1.75 mm
Compatibility: designed for Elegoo Neptune 4 Plus and Neptune 4 Max printers
Printing use: standard extrusion for general-purpose FDM materials (PLA, ABS, etc., subject to material temperature limits)
How to use
Power off the printer and allow the hotend to cool before starting. Remove the old nozzle using an appropriate wrench while holding the heater block steady. Heat the hotend slightly if the nozzle is stuck, then carefully unscrew it. Thread the new brass 0.4 mm nozzle into the hotend by hand to avoid cross-threading, and tighten to the manufacturer's recommended torque with a suitable tool. After installation, perform a test extrusion and calibration to verify proper flow and first-layer settings.
Usage recommendations
Use this nozzle with filaments within their recommended temperature ranges; brass is not suitable for abrasive materials long-term. Regularly inspect the nozzle for wear and clean or replace it when extrusion quality declines. When switching between filament types, purge and heat the hotend appropriately to prevent clogging.
