Nozzle set for Elegoo Centauri Carbon 0.4 mm hardened brass

The 0.4 mm hardened brass nozzle set for the ELEGOO Centauri Carbon is a replacement extrusion nozzle designed to restore or improve print precision. With a 0.4 mm orifice and construction that increases resistance to wear compared with standard brass, this nozzle set supports consistent filament flow and stable thermal performance for everyday filaments on compatible Centauri Carbon printers.

Advantages

Hardened brass construction offers improved abrasion resistance while retaining good thermal conductivity for stable melt conditions. The 0.4 mm orifice delivers a balance between detail and print speed, and the optimized feed geometry helps reduce material leakage and clogging risks. Compact dimensions and standard thread make installation straightforward on compatible hotends.

Suitable for

• Replacing worn or damaged nozzles on ELEGOO Centauri Carbon printers
• Printing standard filaments such as PLA, PETG, and ABS with improved nozzle longevity
• Maintenance and upgrades to restore print quality and dimensional accuracy

When it may not be suitable

This nozzle set is intended for use on ELEGOO Centauri Carbon machines and may not fit other printer models without the same thread and hotend dimensions. While hardened brass increases wear resistance, it is not as hard as hardened steel or specialty nozzles designed for highly abrasive composite filaments containing large amounts of carbon fiber or metal powder.

Key specifications

• Nozzle diameter: 0.4 mm
• Filament compatibility: 1.75 mm filament
• Material: hardened brass
• Thread type: M6
• External dimensions: 6 × 27 mm
• Weight: 3.6 g

How to use

Allow the hotend to heat to the recommended temperature for the filament in use, remove the existing nozzle using an appropriate nozzle wrench, and screw in the replacement 0.4 mm hardened brass nozzle until snug. After installation, perform a short live-heat extrusion and print a calibration object to check for proper flow, bed adhesion, and dimensional accuracy. Tighten when hot if required by the printer manufacturer’s instructions to ensure a secure seal.

What to consider before purchase

• Confirm compatibility with ELEGOO Centauri Carbon hotend and M6 thread
• Choose nozzle diameter appropriate for desired detail and print speed
• Consider filament types you print frequently—hardened brass is better for mildly abrasive filaments but not for very abrasive composites

Usage recommendations

Use this 0.4 mm hardened brass nozzle for routine maintenance and printing common 1.75 mm filaments; perform a calibration print after installation and replace sooner when printing abrasive materials frequently.
