YINGHUA 3D Printer Hotend 300°C Hardened Steel Nozzle Kit 3

SKU CH-TVJ9-AMHG1

High-speed hotend kit with 300°C hardened steel nozzle and CHT nozzles for Ender 3, V2 and CR-10 printers

  • Print at up to 300 °C with a wear-resistant hardened steel nozzle
  • Lightweight hotend with fast-heat conduction block speeds up melt flow
  • Compatible with Ender-3, V-2, CR-10 and Wolong 2.4 printers
  • Kit 3 includes two CHT nozzles in 0.4 and 0.6 mm diameters
  • Silicone sleeve insulates the heating block for stable temperatures

E3 Extrusion Hotend Kit 3

This E3 extrusion hotend kit upgrades compatible Ender 3, Ender 3 V2, CR-10 and Wolong 2.4 printers with a 300 °C hardened steel nozzle assembly. It is built for DIY enthusiasts, educators and professionals who want reliable high-temperature printing on those specific machines.

Kit 3 nozzle bundle

Kit 3 includes the E3 extrusion nozzle, one silicone sleeve and two CHT nozzles sized 0.4 mm and 0.6 mm. The CHT geometry increases melt capacity for faster flow, while the sleeve insulates the heating block and reduces heat creep during extended prints.

300 °C temperature ceiling

The hardened steel nozzle and fast-heat conduction block support materials such as PLA, ABS, PETG, TPU, PC, nylon, PEEK and PEI up to 300 °C. It is not suited for printers outside the listed Ender and CR-10 families or for setups requiring proprietary hotend mounts.

Highlights

  • Print at up to 300 °C with a wear-resistant hardened steel nozzle
  • Lightweight hotend with fast-heat conduction block speeds up melt flow
  • Compatible with Ender-3, V-2, CR-10 and Wolong 2.4 printers
  • Kit 3 includes two CHT nozzles in 0.4 and 0.6 mm diameters
  • Silicone sleeve insulates the heating block for stable temperatures

Questions about this item

How often should I replace the hardened steel nozzles in KIT 3?

The hardened steel nozzles resist abrasion from filled filaments, so they last far longer than brass; swap them only when the tip visibly deforms or extrusion becomes inconsistent.

What temperature limit appears first during a long print?

The hotend is rated to 300 °C, so the firmware or the PTFE liner will reach its ceiling before the metal components do.

Does the silicone sleeve keep the heat block cool enough for all-day runs?

The sleeve insulates the block, reducing radiated heat and stabilising nozzle temperature during extended sessions.
