ELEGOO Hardened Steel Nozzle Set for Neptune 4 Plus/4 Max

The ELEGOO Hardened Steel Nozzle Set for Neptune 4 Plus/4 Max, 5-piece is a replacement kit designed for compatible FDM 3D printers. It provides a direct replacement for worn extrusion components. The hardened steel handles abrasive filaments such as carbon-fibre-filled or wood-filled blends without degrading. Users can swap between different orifice sizes to suit functional components, detailed models and larger structural parts. Selecting the correct size reduces overall printing time while maintaining the required surface finish for specific applications, allowing operators to match the extrusion rate to the demands of each project.

The components are specified for printing temperatures up to 300 °C, making them compatible with high-temperature engineering thermoplastics that require a consistently heated melt zone. Standard brass alternatives wear quickly under abrasive conditions, whereas this hardened steel maintains internal geometry and dimensional accuracy during extended use. The kit delivers consistent extrusion across multiple print cycles without unexpected degradation, and its extended lifespan reduces the frequency of maintenance interventions for users printing with fibre-filled materials.

• Three 0.4 mm nozzles for general-purpose and detailed printing.
• One 0.6 mm nozzle for balancing detail with faster printing speeds.
• One 0.8 mm nozzle for rapid extrusion of larger parts.
• 150 g total weight for compact storage in tool drawers.
• Silver finish that matches typical extruder hardware aesthetics.
• Threading designed for the ELEGOO Neptune 4 Plus and 4 Max for direct fitment.
