All-metal M6 Ø7 mm heatbreak for dual V6 hotend

This stainless-steel all-metal heatbreak is designed for dual hotends using a 7 mm smooth mounting section and an M6 threaded connection to the heater block. It is suitable for 1.75 mm filament and keeps the PTFE tube away from the hottest area of the assembly.

Because the PTFE tube does not extend down to the nozzle, the heatbreak can be used for printing above 260 °C when the heater block, temperature sensor, heater cartridge, wiring and all other hotend components are also rated for the required temperature.

Main features

• All-metal configuration.
• Suitable for 1.75 mm filament.
• Stainless-steel construction.
• M6 thread for the heater block.
• 7 mm smooth section for installation in the heatsink.
• The PTFE tube enters the cold side but does not reach the nozzle.

Compatibility

Designed for the dual V6 Chimera-style hotend for 1.75 mm filament and other assemblies requiring an M6 thread and a 7 mm smooth mounting section.

It is not universal for every hotend described as V6. Before replacing an existing heatbreak, check the thread, smooth-section diameter, required length, heatsink bore and PTFE tube position.

Use and configuration

An all-metal heatbreak is suitable when the PTFE tube must be kept away from the hot zone or when printing materials that require elevated temperatures. PLA and flexible filaments may require more careful adjustment of temperature, cooling and retraction than with a PTFE-lined heatbreak.

The heatbreak alone does not determine the maximum operating temperature of the hotend. Before exceeding 260 °C, check the limits of the thermistor or sensor, heater cartridge, block, wiring, connectors and any nearby PTFE components.

Other versions

For easier feeding of PLA and flexible materials at moderate temperatures, see the M6 Ø7 mm PTFE-lined heatbreak for dual hotends.

A bimetal all-metal M6 Ø7 mm heatbreak for dual hotends and a titanium all-metal M6 Ø7 mm heatbreak for dual hotends are also available. Although they share the same general mounting format, check every relevant dimension before replacing an existing component.

Installation recommendations

• Insert the PTFE tube only as far as the intended stop on the cold side.
• Ensure that the heatsink receives constant and sufficient cooling.
• Perform the final nozzle tightening while hot, following the correct procedure.
• Retune retraction after installation to reduce the risk of jams or molten material being pulled into the cold zone.
