MK8 Nozzle Brass Large 0.5mm (Pack of 2)

The MK8 Brass Large Nozzle is a precision-machined extrusion tip designed for MK8-style hotends used in many popular FDM 3D printers (Creality, Ender series, Anet, Prusa clones and more). The Large nozzles fits printers using the standard size however if you use a silicone sock the sock might not fit over the nozzle. The larger body is intended for a more stable temperature when the part fan is on. Made from high‑quality brass, this nozzle provides excellent thermal transfer for consistent melt and smooth flow with PLA, ABS, PETG and other standard thermoplastics. Available in a range of orifice sizes (commonly 0.2 mm, 0.3 mm, 0.4 mm, 0.6 mm, 0.8 mm), the MK8 nozzle lets you trade off resolution versus print speed and material flow to suit every project — from fine detailed models to rapid prototyping and functional parts.

Key features

• Precision-machined brass for superior thermal conductivity and smooth filament flow
• Compatible with MK8-style extruders / hotends (M6 thread common)
• Multiple nozzle sizes available: 0.2 / 0.3 / 0.4 / 0.5 / 0.6 / 0.8 mm
• Standard M6 thread (verify before ordering) and typical nozzle length for MK8 fittings
• Ideal for common filaments: PLA, ABS, PETG, TPU (soft filaments may require careful retraction tuning)
• Cost-effective and widely used as a replacement or upgrade part

Typical technical specifications

• Material: Brass (CuZn) — non‑hardened
• Thread: M6 (standard MK8)
• Orifice diameters: see SKU (0.2–0.8 mm)
• Overall length: ~13 mm
• Thread Length: ~5 mm
• Recommended nozzle temperature range: 180–260 °C depending on filament type
• Compatibility: MK8 hotends and many clone extruders (verify thread/length compatibility before purchase)

Compatibility & fitment notes

• Confirm your printer uses an MK8-style nozzle with M6 threading. Some all-metal hotends or proprietary systems use different thread pitches or lengths.
• If your hotend has an integrated heat-break/nozzle assembly with nonstandard dimensions, compare overall length and thread depth to avoid gap or over-tightening.
• Use a torque-limited wrench or two wrenches (one on the heater block, one on the nozzle) to avoid twisting the heat-break when installing.

Usage recommendations

• For fine detail prints, use 0.2–0.4 mm nozzles (slower, higher resolution).
• For general-purpose printing, 0.5 mm gives the best balance of speed and detail.
• For faster or stronger prints and thicker layers, use 0.6–0.8 mm nozzles.
• Increase extrusion multiplier / flow and layer height proportionally when using larger nozzle diameters.

Cleaning & maintenance

• Brass nozzles are soft — avoid abrasive filaments (carbon fiber, metal‑filled, glow‑in‑the‑dark) which will wear the orifice; offer hardened or plated options for abrasive filaments.
• Regularly clear partial clogs with cold pulls (nylon/acetone-assisted for ABS) or soak in appropriate solvent if necessary.
• Heat nozzle to printing temp and use a fine needle to remove debris carefully. Do not use excessive force.
• Replace nozzle if orifice becomes irregular or worn to maintain print quality.

Safety & handling

• Always heat the nozzle before attempting removal or cleaning to avoid stripping threads and to make filament removal easier.
• Use heat-resistant gloves and tools when handling the hotend.
• Do not overtighten — tighten firmly at operating temperature then cool to seat threads.
