BZ 3D 3M PFA Teflon Bowden Tube 260 Celsius High Temperature Transparent PTFE tubing 2 X 4mm for 1.75mm Filament Ender 3 CR 10 MK3 MK3S Mega Printer ect.（PFA）

We strive to choose better materials, slower production speeds, higher transparency and more accurate in-tube diameters. High Transparency PFA Tube (260℃+).1.75mm filament ID 2.0mm OD 4mm. The smooth inner space will more effectively reduce the frictional resistance of the filament inside the tube. The high transparency pipe will allow our customers to clearly see the movement of the material through the pipe. Helps 3D printers to be more accurately calibrated and used. PFA is our latest production of a transparent heat-resistant pipe, which can effectively replace the PTFE pipe.It can be installed on 3D printers with different brands and different models. Filament supporting 1.75MM wire diameter. Please be careful not to buy poor quality filament. Because the wire diameter of poor quality filament is not allowed. Uneven filament with uneven thickness will lead to great resistance of feeding tube. This is much better than manufacturing pipes made of FEP materials on the market. Because the FEP tube is an extrusion head that cannot be used in 3D printers.
