LONGER 5pcs 0.4mm M6 Brass Nozzle 3D Printers Accessories

SKU CH-T4MK-ZSN0Z

Pack of five 0.4 mm M6 brass nozzles for 1.75 mm filament FDM printers, compatible with Alfawise U20 and U30 models

  • Five nozzles in one pack for ready spares
  • 4 mm M6 thread fits FDM printers
  • Direct replacement for Alfawise U20 and U30
  • Brass construction with 1.75 mm input and 0.4 mm output
  • New condition ensures clean, undamaged threads

Five-piece brass nozzle set

This pack contains five brass nozzles designed for FDM 3D printers using M6 threading. Each nozzle accepts 1.75 mm filament and extrudes through a 0.4 mm orifice. The set is intended as a direct replacement for worn or damaged tips on compatible machines.

Standard 0.4 mm output diameter

The 0.4 mm bore matches the most common factory specification, so slicer profiles need no adjustment after fitting. Brass construction provides good thermal conductivity for consistent melt flow with PLA, PETG and ABS. Five pieces give enough spares for several months of typical printing.

Suits owners of Alfawise U20 and U30 printers

Makers who run those models can swap nozzles without hunting for thread adapters. Users with printers that require a different thread pitch, a larger bore for composite filaments, or a hardened steel tip for abrasive materials should select a different kit.

Questions about this item

How often should I replace the 0.4 mm brass nozzles when printing abrasive filaments?

Brass wears faster with abrasive materials; swap a nozzle once the 0.4 mm bore widens enough to degrade layer quality.

What limits continuous printing with these M6 nozzles before heat creep becomes an issue?

The 1.75 mm feed path and brass conductivity handle standard PLA and PETG runs; heat creep appears only if cooling airflow drops or retraction settings are excessive.

Do the brass nozzles run hotter or louder than hardened steel during all-day prints?

Brass transfers heat efficiently so the hot-end reaches temperature quickly; noise and power draw stay identical to any M6 nozzle — only wear rate differs.
