## Long description

Brass 0.4 mm nozzle designed for 3D printers Elegoo Neptune 4 and Neptune 4 Pro, compatible with 1.75 mm filament. This precision-milled nozzle replaces the worn or damaged outlet of the hotend to restore consistent extrusion diameter and maintain print dimensional accuracy. The 0.4 mm orifice delivers a balance between print detail and reasonable print speed, making it suitable for everyday FDM tasks with common thermoplastics such as PLA and ABS.
Advantages
The brass construction provides good thermal conductivity for stable melting and smooth filament flow, while the 0.4 mm aperture offers a widely used standard for general-purpose printing. Installation is straightforward and the nozzle is suitable for maintenance replacement to recover lost print quality caused by clogging or wear. Brass nozzles are cost-effective and readily available for routine upkeep of consumer and prosumer 3D printers.
Suitable for
Replacing a worn or clogged nozzle on Elegoo Neptune 4 and Neptune 4 Pro
General-purpose FDM printing with 1.75 mm filament
Printing PLA, ABS and other common thermoplastics at standard layer heights
Maintenance kits and spare parts inventory for desktop 3D printers
Key specifications
Nozzle material: brass
Orifice diameter: 0.4 mm
Filament diameter compatibility: 1.75 mm
Intended printer compatibility: Elegoo Neptune 4, Neptune 4 Pro
How to use
Allow the hotend to reach printing temperature and use proper tools to remove the existing nozzle following the printer manufacturer’s guidance. Screw in the replacement nozzle by hand until snug, then heat the hotend and perform a final torque with a suitable wrench to ensure a secure fit without overtightening. After installation, run a small test print and adjust extrusion multiplier or flow settings if necessary to match the new nozzle’s extrusion characteristics.
Usage recommendations
To prolong nozzle life and reduce clogging risk, use filtered or well-dried filament, avoid printing abrasive composites with this brass nozzle, and perform regular cold pulls or nozzle cleaning procedures as part of routine maintenance.
