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