The UltiMaker Bowden Pack - Decoupler to Print Head (L763, pack of 2) is an OEM spare parts pack for the UltiMaker F Series (Factor 4) industrial 3D printer. Each Bowden tube in the pack measures 763 mm in length and spans the filament path from the decoupler assembly to the print head, forming a critical part of the filament transport system.

The Bowden tubes are PTFE-lined to minimise friction along the filament path and ensure consistent, low-resistance material feed at all printing speeds and temperatures. Over time, the PTFE lining wears, especially with abrasive or high-temperature filaments, leading to increased filament resistance, under-extrusion or jamming. Replacing the tubes with a genuine UltiMaker pack restores smooth filament transport and maintains the reliability of the Factor 4 feeding system. The pack of 2 covers both print head positions or provides one replacement and one spare for uninterrupted production continuity.

Key features

• PTFE-lined Bowden tubes for low-friction filament transport from decoupler to print head on the Factor 4.
• Each tube is precisely 763 mm long, matching the OEM specification for the F Series filament path.
• Pack of 2 tubes covers both print head connections or supplies a replacement and a spare for continuity.
• Restores smooth, consistent filament feed after wear from abrasive or high-temperature engineering materials.
• Genuine UltiMaker OEM parts guarantee correct inner diameter and material compatibility for reliable extrusion.

Compatible with: UltiMaker Factor 4 (F Series)
