The E3D Zodiac Volcano 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 with filament that needs to be printed at very high temperatures. The Zodiac Volcano Pro is made from hardened tool steel and has a double layer coating. This nozzle is 0.40mm, suitable for 1.75mm filament and is specially designed for Volcano heater blocks.
