PTFE tube reduce friction and improve heat resistance, less clogging, less slippage and abrasion on the extruder, better filament glides and more precise printing. This PTFE tube has resistant to high/low temperature, climate,High lubrication, high insulation. Operates in a broad -190 ℃ ~ 260 ℃ range, suitable for diverse environments.ideal for 3D printer parts and DIY. This ptfe tubing can also for heat exchangers, valve cores, transfer of chemical raw materials, transportation of high and low temperature liquids and gases, as well as insulation and heat dissipation. performance of various electronic and communication components.PTFE teflon tubing widely used in electronics, chemicals and industrial.
