[Compatible With Multiple FDM 3D Printers]: This nozzles kit is compatible with for Centauri Carbon/Centauri 3d printers, please confirm your 3D printer model before ordering.<br> [High Precision Nozzles]: The nozzle set is made of high precision CNC machining, with better thermal conductivity and high hardness, smooth and burr-free inner wall, low viscosity coefficient, nozzle error less than 0.02mm, chamfered and rounded to reduce the resistance of the diamond angle to the filament, smoother feeding filament, not easy to clog, to provide you with precise and smooth extrusion printings.<br> [High Quality 3D Printer Parts & Accessories]: Made of high-quality hardened steel, which has a large weight, advanced heat treatment process, and better oxidation resistance, which extends the service life of the nozzle. The contact is flat, solving the problem of filament leakage and effectively preventing printing head leakage. Stable performance and durability. Compatible with most high-temperature and low-temperature printing filaments on the market.<br> Please note:the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!<br> Color:Black<br> Material:Hardening Steel<br> Package Contents:<br> 5 * 0.4mm Nozzles<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
