Phaetus NexTruder Prusa MK4 SiC Nozzle High Flow 21mm³/s for High-Speed Printing, 7X Longer Lifespan Than Hardened Steel, Wear & High-Temp Resistant, Quick-Swap Nozzle Kit for Prusa MK4

The Phaetus SiC Nextruder Prusa Nozzle is an all-metal, quick-swap nozzle designed for Prusa MK4/MK4S/XL/MK3.9/MK3.9S. Its integrated design eliminates leakage, allowing nozzle changes in seconds. The enlarged chamber delivers 21 mm³/s high flow, supporting high-speed printing without under-extrusion. Made of high-hardness silicon carbide (Mohs 9.8) with EndCoat coating (HV3300), it offers extreme wear resistance for abrasive filaments like PA-CF and carbon fiber, with inner diameter change as low as 0.0191mm. It lasts 7X longer than hardened steel nozzles. Compatible with PLA, PETG, ABS, TPU, and industrial composites including glass fiber, steel, wood, and more.

• Quick-Swap Integrated Design – No Leakage, Easy to Swap Specially designed for Prusa MK4/MK4S/XL/MK3.9/MK3.9S. This all-metal integrated silicon carbide nozzle eliminates leakage issues common with assembled nozzles. Quick assembly and disassembly – switch nozzles in seconds
• High Flow for High-Speed Printing The enlarged nozzle chamber delivers a maximum flow rate of 21 mm³/s, supporting high-speed printing without under-extrusion. Perfect for users who want to cut print time without sacrificing quality
• Extreme Wear Resistance for Carbon Fiber & Abrasive Filaments Made of high-hardness silicon carbide (Mohs 9.8) with EndCoat coating (HV3300), this nozzle handles PA-CF, carbon fiber, and other abrasive filaments without wearing out. Pre and post-print inner diameter changes as low as 0.0191mm – your prints stay accurate longer
• 7X Longer Lifespan Compared to Hardened Steel Nozzles Thanks to EndCoat coating and ultra-hard silicon carbide construction, this nozzle outlasts standard hardened steel by up to 7 times – fewer replacements, less downtime
• Wide Compatibility – Beyond Standard Filaments Compatible with PLA, PETG, ABS, and TPU. Also particularly suitable for industrial-grade composite filaments, including carbon fiber, glass fiber, steel, wood, boron carbide, tungsten, and phosphor pigments
