## Summary description

PTFE tube designed for Prusa hotend assemblies, compatible with Prusa MK3S, MK2.5S and MMU2S systems (MPN PSA-15790, EAN 5904422324780). Serves as a heat-resistant liner for filament path inside the hotend, reducing friction and improving filament feeding. Suitable for maintenance, replacement of worn tubing and ensuring reliable extrusion in FDM 3D printing.

## Long description

PTFE Tube for Prusa Hotend — Prusa PSA-15790 for MK3S, MK2.5S, MMU2S is a precision PTFE liner designed to fit inside compatible Prusa hotend assemblies used in FDM 3D printers. The tube provides a low-friction pathway for filament between the extruder and the melt zone, helping to reduce jams and improve consistent filament feeding. It is intended for routine maintenance, replacement of worn PTFE tubing or when upgrading filament handling to maintain reliable extrusion performance.
Advantages
The PTFE tube offers low friction and a smooth bore that minimizes filament stickiness and drag, which supports stable extrusion and reduces risk of clogging. Its heat-resistant properties and precise inner diameter ensure consistent filament guidance across common thermoplastic materials. The component is produced to match the dimensional requirements of the specified Prusa hotend assemblies, allowing straightforward installation and reliable fit.
Suitable for
Replacement of worn or degraded PTFE liners in Prusa MK3S and MK2.5S hotends
Maintenance of MMU2S multi-material feeder systems that use the same hotend path
Improving filament feeding consistency for PLA, PETG and other standard filaments
Repair or preventive service to reduce extrusion issues such as slipping or partial jams
Key specifications
Material: PTFE (polytetrafluoroethylene)
Function: low-friction filament liner for hotend filament path
Compatibility: designed for specified Prusa hotend assemblies used with MK3S, MK2.5S and MMU2S systems
Thermal behaviour: suitable for use as a cold zone liner in typical FDM hotend temperatures (compatible with standard thermoplastic filaments)
Form: precision-cut tubing with smooth internal bore for consistent filament guidance
How to use
Remove the print head or access the hotend following manufacturer service guidance. Extract the old PTFE liner and inspect the hotend throat, heatbreak and nozzle for wear or debris. Insert the new PTFE tube so that it seats correctly against the heatbreak and extruder drive path, trimming the ends if necessary to achieve the recommended length and a flush fit. Reassemble the hotend components, perform a cold and hot filament loading procedure, and run a test extrusion to verify smooth filament movement and correct feeding.
Usage recommendations
Use the PTFE liner for filaments within normal temperature ranges for PTFE-lined hotends (typical PLA, PETG and similar materials). Replace the tube at the first signs of deformation, discoloration, increased friction or recurring jams. When printing high-temperature or abrasive filaments, consider appropriate alternative liners or hardened components designed for elevated temperatures and abrasive resistance.
