Durable Material: for Kobra 2 nozzle is made of hardened steel, with good abrasion resistance, heat resistance, and corrosion resistance, sturdy construction makes it durable enough to serve you for a long time, suitable for 3D printing at high temperatures. Support Filaments: The max temperature of the Hardened Steel nozzle is 500, it can be compatible with PLA, PETG, ABS, TPU, etc 1.75mm Filament. Smooth Inside: Smooth inner wall without burr, minor viscosity coefficient, smoother tapping. smooth contact surface solves the problem of consumables leakage and effectively prevents printing head leakage. High Speed: It's a special hardened steel design so the print head heats evenly. The interior of the nozzle is smooth without burry, which not only reduces air resistance and prevents the filament from jamming. Suitability and Compatibility: Our hardened steel nozzle kits are compatible for Anycubic Kobra 2/Kobra 2 Neo/Kobra 2 Pro/Kobra 2 Plus/Kobra Plus/Kobra Max 3D printers. Please note: the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!
