Five stainless-steel heat breaks for V6 hot-ends

This pack contains five M6 x 22.5 mm throat tubes with a 1.75 mm bore, made from stainless steel and designed to fit V6-style hot-ends on Makerbot 3D printers. The middle section uses M7x1 threads while the lower section that seats in the heater block uses M6x1 threads.

Makers running 1.75 mm PLA

These heat breaks suit owners of V6-style extruders who need replacement or spare throat tubes for 1.75 mm filament. Printers that require a different thread pattern, a different throat length or a larger filament diameter will not accept these parts.

M7x1 upper thread with M6x1 lower thread

The critical specification is the dual-thread profile: M7x1 on the middle portion and M6x1 at the base that enters the heater block. Verify that your hot-end uses this exact thread combination before ordering.

Questions about this item

Should I pick the 5-piece pack or is there a single throat tube option available?

The listing only offers a 5-piece pack of stainless steel throat tubes for V6 Makerbot printers.

What does the 1.75 mm filament rating mean when the tube is installed in my hotend?

The 1.75 mm rating confirms the tube inner bore matches standard 1.75 mm PLA or ABS filament for reliable feeding.

How do the M7 and M6 threads on this heat break affect which heater block I can use?

The middle section uses M7x1 threads for the heat sink while the base uses M6x1 threads that screw into the heater block.
