MK8 - Hercules 1.75mm/.4mm

Collections: Extras, P3-D Hercules Nozzles

Type: Unknown Type

Hercules series nozzles are manufactured using heat treated A2 tool steel which has been hardened completely through. With 50% better heat transfer than stainless steel nozzles, these are the clear cut choice for printing the harshest and most abrasive filaments like carbon fiber and metallics.  Based on testing, wear resistance can be 25x to 100x more than a standard brass nozzle. 

Replaces Makerbot Replicator 2/2X and other nozzles with a 2.18mm inlet bore (for 1.75mm filament).   

Filament Diameter - 1.75mm 

Nozzle Diameter - .4mm
