MK8 Nozzle 1.75 mm—0.4 mm M6 Brass Nozzle for 3D Printers

The MK8 1.75 mm — 0.4 mm Brass Nozzle is a precision-machined extrusion tip designed for FDM 3D printers. Made from high-quality brass, it provides excellent heat conductivity and smooth filament flow, ensuring consistent and detailed printing results. Perfect for PLA, ABS, PETG, and other standard filaments.

📐 Key Specifications

• Model: MK8
• Filament Diameter: 1.75 mm
• Nozzle Orifice Size: 0.4 mm
• Thread Type: M6 × 1.0 (standard hotend thread)
• Material: Brass (CuZn alloy)
• Operating Temperature: Up to 260 °C
• Compatible Printers: Creality Ender series, Anet, Prusa, Anycubic, Artillery, and other MK8-style hotends

🔧 Typical Applications

• High-precision 3D printing with standard filaments
• Prototyping and model making requiring fine detail
• Ideal for PLA, ABS, PETG, TPU, and similar non-abrasive materials
• Replacement nozzle for MK8-compatible extruders

✅ Advantages

• High heat transfer efficiency for stable extrusion temperature
• Accurate orifice machining ensures smooth, uniform filament flow
• Affordable and reliable for everyday 3D printing use
• Lightweight brass design reduces stress on the hotend
• Easy installation with standard M6 threading

⚠️ Considerations

Brass nozzles are best suited for non-abrasive filaments. Avoid using carbon-fiber, glow-in-the-dark, or metal-filled materials, as they can wear out the nozzle tip. For such filaments, use a hardened steel or ruby-tipped nozzle instead. Always heat the hotend before changing the nozzle to prevent thread damage.

🧰 Maintenance Tips

• Clean the nozzle regularly using a soft wire or cleaning needle
• Perform a “cold pull” to remove filament residue when needed
• Check for wear or deformation after extended use
• Store spare nozzles in a dry environment to avoid oxidation

📦 Summary

The MK8 1.75 mm — 0.4 mm Brass Nozzle delivers excellent print quality and reliability for FDM 3D printers. Its smooth internal bore, precise machining, and efficient heat transfer make it a perfect choice for detailed, clean, and consistent prints using standard filaments.
