Hot End

Complete Kit

Hotend Kit Complete drop-in replacement with heat break, thermistor, heater cartridge and 0.4 nozzle.



The heatblock is mounted to the extruder with two M2.5x10mm socket head cap screws (SHCS).



Sovol SV06 uses standard MK8 nozzles with M6 thread, specifically a Creality MK nozzle used in CR-6 SE, Ender S1 and Sprite extruders from Creality. Any MK8 nozzle with M6 thread will also work with SV06's hotend. If a nozzle is a lot shorter you will need to adjust the ABL probe height.

If you want the ones similar to original one search for "Creality MK", "CR-6 SE" or "Ender S1" nozzle
