PTFE tubing which is a high-quality material suitable for FDM printers. PTFE tubing can be used in extreme temperatures and in harsh chemical environments. It's chemically inert, has low permeability, and has the lowest friction coefficient of any tubing. Temperature range is -450 to 500°>F; melts at 620°>F.Our Teflon tube is made of PTFE material and has excellent properties such as heat resistance and corrosion resistance, meeting the needs of different users. We offer various sizes to cater to different printer models and needs. In addition, this tube has excellent self-lubrication properties that reduce filament-to-pipe friction and improve print quality.
