Replace your teflon tube to keep your extruder running in top shape and prevent thin-wall conditions or holes from developing (see example photos). Over time, the soft teflon gives way to the plastic being pushed against the same spot and eventually results in worn thru tubes, creating extrusion or loading/unloading issues.

Tubes are available for both the “original” and “updated” versions of flashforge creator extruder hot-ends. The original version uses a 3mm OD tube, while the updated version uses a 4mm OD tube. Please verify your type before ordering. Both are 2mm ID (meant for 1.75mm filament). Tubes should also work for other extruders which utilize teflon tubes.
