## Summary description

PTFE tube manufactured for Prusa hotends, compatible with Prusa MK3, MK2.5, MK2S and MMU2 setups. The tube serves as a low-friction filament guide inside the hotend assembly, suitable for PLA and other common filaments. Use it to replace worn or degraded liners, restore reliable filament feeding and reduce jams in multi-material or single-extruder prints.

## Long description

Prusa PTFE Tube for Hotend is a precision-cut low-friction filament liner designed for Prusa MK3, MK2.5, MK2S and MMU2 hotend assemblies. Manufactured to fit the original hotend geometry, the PTFE tube provides a smooth filament path inside the hotend, helping to maintain consistent extrusion and reduce the risk of jams caused by worn or degraded liners. It is suitable for common thermoplastic filaments such as PLA and other materials that benefit from a PTFE-lined feed path.
Advantages
The PTFE tube offers a low coefficient of friction and stable inner surface that minimizes filament resistance and improves feeding reliability. Because it is manufactured specifically for Prusa hotends, it restores the correct internal clearances and seating inside the hotend assembly, which helps maintain consistent extrusion behavior. The tube is resistant to common thermal and mechanical wear encountered in desktop 3D printing and makes replacements fast and straightforward.
Suitable for
Replacing worn or degraded hotend liners in Prusa MK3, MK2.5, MK2S and MMU2 setups
Restoring reliable filament feeding after frequent printing or multi-material jobs
Use with PLA and other filaments that require a PTFE-lined feed path
Maintenance tasks to reduce under-extrusion and filament hang-ups
Key specifications
Material: PTFE (polytetrafluoroethylene)
Designed inner surface: low-friction smooth bore for filament guidance
Compatibility: fits Prusa MK3, MK2.5, MK2S and MMU2 hotend assemblies
Function: filament liner for hotend to reduce jams and improve feed consistency
How to use
Power off and cool the printer before performing any hotend maintenance. Remove the existing liner according to the Prusa service instructions, then insert the new PTFE tube into the hotend until it seats against the designated stop. Cut or trim the tube to the recommended length if required by your specific hotend variant, ensuring a clean, square end to avoid filament guidance issues. Reassemble the hotend components and perform a cold or heat-assisted filament loading and extrusion test to confirm correct installation and flow.
Usage recommendations
Inspect the PTFE liner periodically for signs of deformation, burn marks, or contamination. Replace the tube if you observe increased extrusion resistance, stringing, or frequent clogs. Use the PTFE liner with filaments compatible with PTFE-lined paths and avoid prolonged exposure to temperatures above PTFE’s recommended limits to prevent degradation.
