Bimetal - high quality
Trianglelab all-metal bimetal heatbreak for dual V6-style hotends, with an M6 thread for the heater block and a smooth Ø7mm upper body for retention in a compatible heatsink. It is designed for 1.75mm filament.
It combines a polished stainless-steel centre tube with two copper-alloy sections. This design concentrates the thermal break in a very narrow area and helps the heatsink keep filament cold before it enters the melt zone.
Main features
- All-metal filament path with no PTFE in the hot zone.
- Polished Ø1.9mm bore for nominal 1.75mm filament.
- Nominal smooth Ø7mm cold-side body, which is different from an M7 thread.
- Three-piece construction that thermally separates the heater block and heatsink.
The manufacturer rates this heatbreak family up to 450°C, but that value must not be applied to the complete hotend. Always respect the lowest limit of the installed sensor, heater, block, nozzle, wiring and control system.

Dual-hotend compatibility
The smooth Ø7mm body is intended for heatsinks that secure each heatbreak through a matching bore and retention system, such as the Chimera-style aluminium dual heatsink for two V6 hotends. Before ordering, check the actual bore diameter, insertion depth and retention method.
The M6 end can use V6 blocks with matching threads and sealing geometry, such as the standard V6 thermistor block, the V6 block for 3mm sensors or the Brass V6 block for 3mm sensors.
It is not interchangeable with a threaded M7 heatbreak, and it should not be selected only because another heatbreak measures approximately 7mm. Length, retention and nozzle sealing must also match. If your heatsink has a female M7 thread, use the Trianglelab M6/M7 heatbreak.
Dual-system installation and setup
- Insert the smooth body into the heatsink's Ø7mm bore and secure it with the correct retention system.
- Thread the M6 end into the block and adjust the nozzle so that it seals against the heatbreak inside the block.
- Hold the block during tightening and do not twist the thin centre tube.
- Check that both heatbreaks receive even cooling and that both nozzle tips are correctly aligned in height.
- Review Z offset, retraction and PID control if mechanical or thermal behaviour changes after installation.
The heatbreak requires no dedicated firmware parameter. A dual system must still have the nozzle offset and extruder-selection method configured correctly for the machine's electronics and firmware.
Choose it if…
- Your dual heatsink uses nominal Ø7mm smooth heatbreaks and M6 heater blocks.
- You want an all-metal path and a sharper thermal transition.
- You can verify and adjust retention, cooling and both nozzle heights.
Do not choose it if…
- Your heatsink uses an M7 thread or a smooth heatbreak of a different length.
- You need a direct replacement for a Creality, Revo, Dragon, Rapido, CHC or another proprietary hotend without comparing every dimension.
- You cannot perform hot tightening and subsequent nozzle alignment.
Package contents: 1 Trianglelab M6/Ø7mm bimetal heatbreak. Heater block, heatsink, nozzle and PTFE tube are not included.
