About this part

Choose this 0.4 mm brass nozzle when your MK4 or XL has the Nextruder and you want to keep a familiar opening for ordinary filament. If you routinely print a filled material that requires a wear-resistant nozzle, compare the coated version and the filament maker’s minimum opening.

Questions before buying

Which marking should I check before installation?

E3D identifies the 0.40 mm version in its brass Nextruder range with three dots. Check the size on the pack and in the slicer.

Does this make sense for my first like-for-like replacement?

It is a native-format choice for a listed MK4 or XL when you already print at 0.4 mm and your material suits brass.

Should I move to High Flow if I only need a spare?

Keep a standard-flow part if your current profile suits the job. Compare the High Flow brass variant when its geometry and matching profile are useful.
