🌟 Prusa Nextruder Brass Nozzle (0.4 mm)
The Nextruder Brass Nozzle is the official replacement nozzle from Prusa for the Nextruder, available in various diameters. Unlike conventional nozzles, the Prusa Nozzle integrates the nozzle and heatbreak into a single all-metal piece — completely eliminating the PTFE tube from the filament path for greater reliability, support for higher temperatures, and much faster nozzle changes. Compatible with MK4, MK4S, MK3.9, MK3.9S, XL, CORE One, CORE One+, and CORE One L printers.
🔹 What sets the Prusa Nextruder Brass Nozzle apart?
- Nozzle and heatbreak integrated into a single piece — unique Prusa all-metal design that eliminates the PTFE tube from the filament path for greater reliability and high-temperature support.
- All-metal filament path — no PTFE anywhere in the path, for safer printing at high temperatures and with technical materials.
- Much faster nozzle change — direct fit into the Nextruder without needing to disassemble additional components.
- High-precision brass — excellent thermal conductivity for uniform filament melting and quality finish.
- 0.4 mm nozzle — the industry standard diameter, ideal for the perfect balance between detail and print speed.
- Official Prusa nozzle — guaranteed quality and compatibility with the entire Nextruder family.
- Compatible with V6 via adapter — if you prefer third-party V6 nozzles, the Nextruder-to-V6 adapter is available separately.
