Grey PTFE Tube (By the Metre) – 2.5x4mm – Bambu Lab A1 AMS Lite

Description

Replacement PTFE Tube for Bambu Lab A1 & AMS Lite

This grey 2.5 × 4 mm PTFE tube is a direct replacement for the filament feed tube used in Bambu Lab A1, A1 Mini, P1P, P1S, and AMS Lite systems. PTFE tubes are a wear item — over time the inner bore develops scoring and drag marks from filament feeding, which increases friction, causes inconsistent extrusion, and can lead to AMS feed failures. Replacing worn PTFE tube restores smooth, reliable filament feeding.

Sold by the metre — each quantity of 1 equals one metre of tube. Need 2 metres? Select quantity 2.

When to Replace

Increased filament feeding resistance or AMS load failures, visible scoring or discolouration inside the tube, filament grinding at the extruder due to increased drag, stringing or under-extrusion caused by inconsistent feeding, and any time you’re doing a full hotend service or maintenance.
