Low Resistance Star Shaped PTFE Tube for 1.75mm Filament

### Star Shaped Inner Wall Reduces Friction by 30% 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 approximately 30% compared to traditional round tubes. ### Low Friction Stable Feeding for High Speed Printing 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 270mm/s and frequent filament changes. Friction coefficient as low as 0.03. ### 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 high purity PTFE material that withstands temperatures as high as 260°C without carbonization or brittleness. Perfect for printing ABS, nylon, and other engineering grade filaments without deformation or performance loss. ### Translucent White Design for Visual Monitoring The semi transparent white tube allows you to easily see filament movement and identify breakage or feeding issues instantly. Flexible construction fits Bowden setups, AMS routing, and other filament paths. Compatible with all 3D printers using 1.75mm filament including Bambu Lab, Creality, Prusa, Anycubic, and Voron.
