Longer5pcs 3D Printer Nozzle 0.4mm MK8 Brass 3D Print Head M6 1.75mm for 3D Printers

These replacements nozzles are for a backup if I get a clogged tip. It's to to have some on hand because they never clog when it convenient.

I love these nozels. I have only had to use one as a replacement but they are very smooth.

Shorter than standard threaded section fits LK4 Pro perfectly.

Good nozzle replacement for my 3D printer machine. These nozzles fit perfectly, no problems so far. Very nice set of nozzles. This is exactly what I needed. Thank you so much.
