Upgrade your ELEGOO Neptune 4 3D printer with the ELEGOO Brass Big Flow Nozzle, designed to deliver high-volume extrusion, improved heat transfer, and exceptional print stability. Available in 0.2mm, 0.6mm, 0.8mm, and 1.0mm nozzle diameters, this nozzle series offers the perfect combination of precision and speed for every type of project.

Constructed from premium-grade brass, each nozzle provides excellent thermal conductivity, ensuring fast, consistent heating and smooth filament flow. The optimized internal channel reduces friction and prevents clogging, resulting in cleaner surfaces, sharper details, and highly reliable extrusion during long or high-speed prints.

With precise machining and a standard thread compatible with Neptune 4, the ELEGOO Brass Big Flow Nozzle installs securely and aligns perfectly with the hotend. Whether you are printing ultra-detailed models with a fine nozzle or producing strong, large components with a bigger orifice, this nozzle series ensures outstanding performance.

Compatible with a wide range of filaments—including PLA, ABS, PETG, TPU, and more—these nozzles are ideal for hobbyists, professional makers, and engineering projects.

At Protomont Technologies, we provide high-quality 3D printer parts and upgrades for the Indian 3D printing community. Enhance your Neptune 4 printing performance with the Brass Big Flow Nozzle Series from ELEGOO.
