💡 What is PTFE tubing used for in 3D printer hotend assemblies?
PTFE tubing provides a heat-safe, low-friction path for filament from the extruder into the hot end.
- It offers a low-friction path for smooth filament movement
- It resists temperatures up to 260°C in enclosed hot ends
- It requires secure fittings such as PC4-M6 or PC4-M10 to prevent leaks
