This is a replacement heat break for the Gulfcoast Robotics MK10 All Metal Hotend. Not compatible with the Micro Swiss or stock cooling blocks.
This one piece, stainless steel heat break uses external M7x1 threads, which lock securely inside of our modified cooling block. The inner bore has been precision reamed for a smooth surface finish, which helps to prevent filament jams and clogs.
