Official Creality K1C Nozzles 0.4mm, Unicorn Quick-Swap Ender 3 V3 Nozzle with Titanium Alloy Heat Break, Copper Alloy and Hardened Steel for Creality K1C/Ender 3 V3/Ender 3 V3 Plus 3D Printers(2PCS)

Me funcionaron perfecto con mi Creality K1C.

This original Creality nozzle and hotend assembly is a fantastic replacement/upgrade. The copper body provides excellent thermal conductivity, and the titanium alloy heat break is a game-changer for preventing heat creep and nozzle clogs, even when frequently switching between different filament types like standard PLA and specialty silks. It fits perfectly, heats up quickly and evenly, and delivers incredibly smooth extrusion. Filament flows flawlessly without any jamming. A reliable, high-quality part that keeps my machine running perfectly. Highly recommended!

Nozzles work as they are intended. I find it cheaper this way then to declog a super clogged nozzle. I get roughly 6 months out of these nozzles and no issue with them after all these are a wear item. They come with the thermal compound also so that's a bonus.

Will never use anything other than these. Never have issues. Long as you use filament that clears the nozzles between material changes. Will prevent random clogs due to difference of materials and different melting temps.

Easy to replace and a good idea to have avaliable before you need it.
