Product description: Nextruder hotend head with 0.4 mm brass nozzle for Prusa MK4, XL, MK3.9, MK4S and CORE One 3D printers - assembled

Hotend with brass nozzle 0.4 mm is an original Prusa brand kit, designed for the latest models of 3D printers based on the Nextruder system . Compatible with MK4, MK4S , MK3.9 , XL and CORE One devices, this kit provides reliability, temperature stability and ease of use. The hotend design is based on an all-metal filament track in the heating zone , which eliminates the need for a PTFE tube in the critical area. Thanks to this, you can use a wider range of filaments, including materials with higher temperature requirements.
