Used on the inside of nozzles and throat tubes, these degrade over time.

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.
