All metal heat break 1.75mm

This heat break has feeding problems, every now and then the printer cant push the filament through.

Works for the higher temp filaments however does require some finishing if you want it to perform better. There's a few guides online for polishing..

Very very unhappy with this heat break. Firstly, it didn't want to fit into the heat sink - had to shave off a little bit from the outside of the heat break. Then I found that the filament wasn't going through the heat break because the hole was too small at the end. Absolutely frustrated with this heat break
