Intended for maintenance or repair, it simplifies filament feeding and supports reliable prints.

## Long description

PTFE Tube Renkforce RF-5491864 for 3D Printer Pro 7 Dual — PTFE Bowden filament guide is a genuine replacement PTFE liner intended for use in Bowden-style filament feed systems of the 3D Printer Pro 7 Dual. The smooth inner surface of the PTFE tube reduces filament friction and helps maintain consistent extrusion flow. Designed for maintenance and repair, the tube supports reliable filament transport and reduces the risk of clogging or grinding in the filament path.
Advantages
The PTFE material offers low friction and thermal stability suitable for typical desktop 3D printing temperatures, which helps minimize resistance and wear on filament. Being a straight replacement part, the tube preserves original feed geometry and compatibility with existing Bowden fittings and connectors of the printer. Its consistent inner diameter contributes to steady filament movement and improved extrusion consistency, while the chemically inert surface resists filament residue buildup.
Suitable for
 Replacement of worn or damaged Bowden liners in 3D Printer Pro 7 Dual
 Routine maintenance to restore smooth filament feeding
 Reducing filament jams and extrusion inconsistencies
 Use with common thermoplastic filaments in Bowden setups
Key specifications
 Material: polytetrafluoroethylene (PTFE)
 Function: Bowden filament guide / liner
 Compatibility: designed for use with 3D Printer Pro 7 Dual Bowden feed path
 Inner surface: smooth, low-friction bore
 Typical thermal range: suitable for standard desktop 3D printing temperatures where PTFE liners are normally used
How to use
Turn off and cool the printer before performing maintenance. Remove the existing Bowden tube or liner according to the printer manufacturer’s service instructions, then slide the replacement PTFE tube into place ensuring it seats fully in the feeder and hotend couplings. Trim the ends squarely if required to ensure tight connections at push-fit couplers. After installation, perform a filament loading procedure and run a short extrusion test to confirm smooth feed and correct nozzle flow.
Usage recommendations
Use the PTFE tube within the typical temperature limits for PTFE-lined Bowden systems; avoid prolonged exposure to temperatures above those recommended for PTFE liners. Inspect the tube periodically for signs of wear, deformation, or filament residue and replace it when performance degrades. When printing at higher nozzle temperatures or with abrasive filaments, consider appropriate nozzle and drive adjustments to maintain reliable feeding.
