ELEGOO Centauri Carbon 0.8 mm Brass Hardened Steel Nozzle Kit is a robust replacement nozzle designed for reliable extrusion and extended durability. Constructed with a hardened steel core and precision-machined brass exterior, this 0.8 mm nozzle resists wear from abrasive and composite filaments while maintaining smooth material flow. The larger 0.8 mm aperture supports faster printing and stronger layer bonding, making it ideal for printing functional parts and larger models using PLA, PETG, ABS, TPU, carbon-fiber blends, and other specialty filaments. Precision threading and secure fit ensure stable thermal transfer and consistent performance across a wide range of 3D printers compatible with E3D-style nozzles.
