PTFE tube for BambuLab AMS and X1/P1 series printers – 4 m, grey

PTFE tube for BambuLab AMS and X1/P1 series printers – 4 m, grey is a replacement PTFE liner intended for BambuLab AMS filament management systems and X1/P1 series 3D printers. The 4-meter grey tube provides a smooth, low-friction internal surface that helps filament feed reliably through Bowden-style paths and filament guides. It is sized and finished for use in setups that require PTFE tubing for maintenance, replacement, or longer filament runs.

Advantages

The PTFE material offers low friction and thermal stability, reducing filament drag and improving retraction response. A consistent inner bore and smooth surface minimize filament snags and abrasion, while the grey outer finish makes routing and visual inspection easier. The 4 m length covers multiple guide paths or allows staged replacements without cutting short supply.

Suitable for

• BambuLab AMS filament guide assemblies and extensions
• X1 and P1 series printers using Bowden or guided filament paths
• Maintenance and replacement of worn or damaged PTFE liners
• Extended filament runs where longer continuous tubing is required

Key specifications

• Material: PTFE (polytetrafluoroethylene) with low-friction inner surface
• Length: 4 meters of continuous tubing
• Color: grey outer finish for easier identification
• Intended use: filament liner for guided or Bowden-style filament routing
• Compatibility: designed for BambuLab AMS systems and X1/P1 series printer filament paths

How to use

Cut the PTFE tube to the required length and insert it into the filament guide or AMS channel according to the printer or AMS instructions. Ensure ends are cut square to prevent filament catching and push the tube firmly into connectors or couplers to form a secure, continuous filament path. When installing in Bowden arrangements, check routing for smooth bends without kinks and verify that fittings compress the tubing evenly to avoid gaps.

Usage recommendations

For best performance, replace PTFE liners when signs of wear, deformation, or increased extrusion resistance appear. Use clean, square cuts and appropriate couplers compatible with the printer’s guide system. Store unused tubing away from direct sunlight and high heat to preserve material properties.
