## DLC Hardened Steel Extruder Gear for Elegoo Neptune 4 Series The **DLC Hardened Steel Extruder Gear for Elegoo Neptune 4 Series** is a compatible replacement designed for the Elegoo Neptune 4, Neptune 4 Pro, Neptune 4 Max and Neptune 4 Plus 3D printers. It provides a practical replacement for an extruder gear that has become worn, damaged or unable to feed filament consistently. Manufactured from hardened steel with a DLC coating, the gear is designed to provide improved surface hardness and wear resistance during regular filament feeding. The durable construction makes it especially useful for printers frequently used with abrasive materials that can accelerate wear on standard extruder components. A worn extruder gear may cause filament slipping, inconsistent extrusion, under-extrusion, visible layer defects or unreliable filament loading. Replacing the affected gear can help restore consistent filament grip and dependable material feeding when the extruder gear has been confirmed as the source of the problem. This is a compatible aftermarket spare part and is not manufactured or supplied as an original Elegoo component. ### Key Features – Compatible with the Elegoo Neptune 4 Series – Hardened steel construction – DLC wear-resistant coating – Designed for consistent filament grip – Helps restore reliable filament feeding – Suitable for standard and abrasive filaments – Practical replacement for a worn extruder gear – Suitable for printer maintenance and repairs – Compatible aftermarket spare part – Not an original Elegoo product ### Compatible Printers – Elegoo Neptune 4 – Elegoo Neptune 4 Pro – Elegoo Neptune 4 Max – Elegoo Neptune 4 Plus ### Applications – Replacing a worn extruder gear – Repairing filament slipping – Resolving inconsistent material feeding – Reducing under-extrusion caused by poor filament grip – Maintaining printers used with abrasive filament – General extruder maintenance and repairs ### Technical Specifications **Product:** Extruder Gear **Compatibility:** Elegoo Neptune 4 Series **Material:** Hardened Steel **Surface Treatment:** DLC Coating **Function:** Filament Feeding **Installation:** Compatible replacement **Condition:** Aftermarket spare part **Manufacturer Status:** Not an original Elegoo product ### Package Includes – 1 × DLC Hardened Steel Extruder Gear for Elegoo Neptune 4 Series Restore dependable filament feeding with the **DLC Hardened Steel Extruder Gear for Elegoo Neptune 4 Series**, a wear-resistant compatible replacement for the Neptune 4, Neptune 4 Pro, Neptune 4 Max and Neptune 4 Plus.
