0.25mm Brass Nozzle for Prusa MK4S, CORE One, One L, XL

The Prusa brass nozzle with a 0.25 mm diameter is a high-precision all-metal nozzle specifically designed for the Nextruder. It combines the nozzle and heatbreak into a single component, significantly simplifying and speeding up nozzle changes. The entire filament path through the Nextruder is made of metal, eliminating the need for PTFE tubing. This all-metal design improves the overall reliability of the printer and allows for higher temperature operation. The nozzle is made of brass, a material with excellent thermal conductivity, particularly suitable for standard filaments like PLA, PETG, and ABS. The fine nozzle diameter of 0.25 mm enables highly detailed prints with high resolution. The nozzle is compatible with printer models MK4, MK4S, MK3.9, MK3.9S, XL, XL+, CORE One, CORE One+, CORE One+ (Gen 2), CORE One L, and CORE One L+. For users who wish to continue using V6-compatible nozzles, Prusa offers a separate Nextruder-to-V6 adapter. Installation is tool-free and completed in just a few steps thanks to the all-metal construction.
