UltiMaker Bowden Pack L850 (S Series) 80-227177

Replacement Bowden tube set for large-format UltiMaker S-series

The Bowden pack L850 is a high-performance filament delivery system specifically designed for the expanded build volumes of the UltiMaker S5, S7, and S8. These 850 mm tubes provide the necessary length to allow the print head to reach every corner of the large build plate without straining the filament path. Manufactured from premium, low-friction PTFE, these tubes ensure that 2.85 mm filament glides smoothly from the rear feeders to the dual-extrusion print head, which is essential for maintaining consistent extrusion pressure and sharp retraction performance.

Bowden tubes are consumable components that can degrade over time. Abrasive filaments can score the internal walls, while the constant mechanical stress of printing can cause the ends to lose their circular profile. If you notice increased "stringing," under-extrusion, or if the tubes appear discoloured and cloudy, replacing them with this genuine L850 set will restore the industrial-grade reliability and precision of your large-format S-series machine.

What is in the pack?

• 2x Bowden tubes (850 mm): Precision-extruded PTFE tubes optimised for the wide-span gantry of the S5, S7, and S8.
• 4x Collets: Industrial metal-toothed inserts that lock the tubes into place, preventing movement during high-speed retractions.
• 2x White clamp clips: Specifically designed to secure the tubes at the print head entry points.
• 2x Black clamp clips: Specifically designed to secure the tubes at the feeder exit points.

Compatibility:

This Bowden set is designed exclusively for the following large-format models:

• UltiMaker S7
• UltiMaker S5 (and S5 Pro Bundle)
• UltiMaker S8

Note: These 850 mm tubes are too long for the UltiMaker S3, 2+ Connect, or Factor 4.
