Fit For 3D Printers Models: The all-metal hotend nozzle with throat tube heatbreak is compatible with Anycubic Kobra X/Kobra 4 FDM 3d printers, please confirm your 3D printer model before ordering.
Easy To Install: The quick-swap hotend nozzle, which can be tightly connected to the heating block, is easy to install, and can be easily assembled to the inside of the hot end, which is stable and not easy to fall off.
Smooth Feeding, No Leakage: 45° chamfering design at the threads of the throat tube, smooth feeding, flat and smooth cross-section of the throat tube, and highly close to the butt fittings, which can ensure smooth feeding and no leakage.
Smooth Inner Wall: The interior of hotend nozzle throat tube has been treated with a special process, the inner wall is smooth and burr-free, compared with ordinary throat tubes, the resistance of print back pumping is reduced by 90%, so that the finished printing models is printed with higher precision and finer.
Hardened Steel Material, High Temperature Resistance: Full metal has good heat insulation, high temperature resistance, and can withstand up to 400℃-500℃, internal hole roughness < 0.4, corrosion and wear resistance.
