The E3D Zodiac MK8 PRO nozzle is designed to be even more wear-resistant than the CRB nozzles. This Pro nozzle can be used with temperatures up to 450℃. This makes it ideal for use in combination with filament that must be printed at very high temperatures. The Zodiac MK8 Pro is made of hardened tool steel and has a double-layer coating. This nozzle is 0.40mm, suitable for 1.75mm filament and is specially designed for MK8 hotends.
