This is a replacement HeatBreak for E3D-v6 1.75mm Universal HotEnds.
Since v5, the manufacturing processes for all our HeatBreaks has been overhauled to achieve a better internal surface finish than ever before. The improved internal surface finish will help to reduce extrusion force and improve relliability on retractions.
- This v6 HeatBreak is not compatible with it's v5 predecessor on the cold side (i.e. the heatsink).
