## Summary description

PTFE tube designed as a hotend liner for Prusa 3D printers, compatible with the Prusa i3 MK3S+ and i3 MK3S+ configured with MMU2S. Serves as a low-friction filament guide inside the hotend, suitable for standard filaments that require a PTFE-lined thermal path. Used for replacing worn or degraded liners to restore filament flow and reduce jamming in multi-material setups.

## Long description

PTFE Tube for Prusa Hotend — Prusa i3 MK3S+ / MK3S+ with MMU2S is a precision-made internal liner designed to guide filament through the thermal path of compatible Prusa hotends. This replacement PTFE liner restores the low-friction environment required for reliable extrusion of standard filaments, helping to reduce filament drag, stringing and jams in single- and multi-material setups. It is intended for use with the Prusa i3 MK3S+ and i3 MK3S+ equipped with the MMU2S unit and matches the dimensional and material requirements of those hotends.
Advantages
The PTFE liner is manufactured from high-quality polytetrafluoroethylene to provide a smooth, low-friction surface that improves filament flow and reduces the chance of jams. It offers consistent internal diameter and thermal stability across typical printing temperatures for PTFE-lined hotends, allowing predictable extrusion behaviour. As a direct replacement liner for Prusa hotends, it simplifies maintenance and helps restore original performance without the need to replace the entire hotend assembly.
Suitable for
 Replacement of worn or degraded hotend PTFE liners on Prusa i3 MK3S+ printers
 Prusa i3 MK3S+ printers configured with MMU2S for multi-material printing
 Standard filaments that require a PTFE-lined thermal path (PLA, PETG, some flexible filaments)
 Routine maintenance to prevent extrusion issues and reduce jamming
Key specifications
 Material: PTFE (polytetrafluoroethylene)
 Designed inner surface: low-friction, smooth bore for consistent filament guidance
 Compatibility: Prusa i3 MK3S+ hotend geometry and MMU2S multi-material configuration
 Function: Hotend liner for a PTFE-lined thermal path to support standard filament extrusion
How to use
To replace the PTFE liner, power down and cool the printer fully, then disassemble the heatbreak or hotend according to Prusa’s maintenance instructions. Remove the old liner and slide the new PTFE tube into position, ensuring it seats flush with the required hotend interfaces and that filament can pass through unobstructed. Reassemble the hotend components, check for correct seating and clear filament path, then perform a cold extrusion or calibration print to verify proper function.
Usage recommendations
Use this PTFE tube with standard thermoplastic filaments and within the temperature range recommended for PTFE-lined hotends. Inspect the liner periodically for signs of wear, deformation or contamination, and replace if extrusion problems persist. Avoid prolonged use at temperatures above those advised for PTFE-lined thermal paths to prevent material degradation.
