### Star Shaped Inner Wall Design This PTFE tube features a unique flower pattern or star shaped cross section. The concave convex design significantly reduces contact area between filament and tube wall, lowering friction resistance by 30 percent compared to traditional round tubes. Low Friction Stable Feeding The special geometric inner wall ensures smoother filament feeding, effectively eliminating clogs and grinding issues. It maintains stable material delivery during high speed printing up to 500mm per second and frequent filament changes. ### TPU and Flexible Filament Friendly Flexible filaments like TPU below 95A hardness are prone to buckling in standard PTFE tubes. The star shaped inner wall solves this problem, allowing soft materials to feed smoothly every time without getting stuck. ### High Temperature Resistance Up to 260°C Made from premium PTFE material that withstands temperatures as high as 260°C. Perfect for printing ABS, nylon, and other engineering grade filaments without deformation or performance loss. ### 5 Meter Length Universal Compatibility The 5 meter continuous length allows for multiple replacements or custom routing on large format printers. Compatible with all 3D printers using 1.75mm filament including Creality, Bambu Lab, Prusa, Voron, Anycubic, and Elegoo. The semi transparent white color lets you monitor filament movement and identify breakage issues easily.
