All-metal heatbreak with M7 thread for 1.75mm filament and 37.6mm total length

  • All-metal construction withstands high printing temperatures
  • Smooth inner bore reduces filament clogging during extrusion
  • M7 thread fits E3D V6 hot-end assemblies directly
  • Designed for 1.75 mm filament compatibility
  • 6 mm total length matches standard heat-break dimensions

Compatible Heatbreak for E3D V6 Hotends

This all-metal heatbreak fits E3D V6 hotends and volcano heat blocks. It accepts 1.75mm filament and uses an M7 thread. The total length is 37.6mm, matching the threaded specification for these printers.

Integration With Extruder Assembly

The heatbreak threads into the heater block and seats inside the heatsink. Its smooth inner wall reduces filament friction and helps prevent clogging during prints. No additional adapters are required when replacing a worn or damaged heatbreak on a compatible V6 setup.

Thermal Performance and Power Draw

All-metal construction withstands high printing temperatures without deforming. The component itself draws no power and adds no active cooling noise. It relies on the printer's existing heatsink fan to maintain a sharp thermal transition between the cold and hot zones.

Questions about this item

How hot can the all-metal heatbreak get before the PTFE tube fails?

The heatbreak is all-metal with no PTFE liner, so it handles the full hot-end temperature range of your V6 heater block.

Will the M7 thread fit my existing V6 heatsink without cross-threading?

The M7 thread matches the standard V6 heatsink interface; screw it in by hand until snug, then tighten gently with a 7 mm spanner.

Does the 37.6 mm length match the stock heatbreak on my Prusa i3 MK3?

Yes, the 37.6 mm threaded length is the same as the original E3D V6 heatbreak used on the MK3.
