Unique-Bargains V6 Heat Break M6x22.5mm 1.75mm 5pc

V6 Heat Break 1.75mm Filament Compatibility

This pack supplies five stainless-steel heat breaks built for V6-style hot-ends that accept 1.75mm filament. Each throat measures 22.5mm long with a 4mm to 3mm internal bore and ships with a PTFE liner. The parts are intended for makers running PLA or ABS on compatible printers.

M7 and M6 Threaded Interface Requirements

The middle section carries an M7x1 thread while the base that seats in the heater block uses M6x1, so the surrounding heat sink and block must match both pitches. Installing the included PTFE tube completes the filament path and removes the need for a separate liner purchase. Builders whose hot-ends use a different thread pattern cannot use these throats.

Stainless Steel Body Under Continuous Extrusion

The stainless-steel construction resists deformation during long print jobs where the heat break sits at the thermal transition zone. Consistent filament flow depends on the PTFE liner staying seated and the threads remaining tight through repeated heat cycles. Printers that demand a longer throat or a different internal diameter will not match this 22.5mm design.
