About this item

• 【PTFE tube for 1.75mm filament】The 3 mm ID × 4 mm OD design offers a more streamlined filament pathway compared to standard 2 mm tubes, significantly reducing clogging risks and enhancing printing consistency.
• 【Designed for Direct Drive Systems】Specifically engineered for Direct Drive Extruder printers—such as the Bambu Lab A1/A1 mini/P1P/P1S/X1C and Creality K1/K1 Max/Ender 3 V3—this tube ensures a consistently smooth filament delivery for enhanced print quality.
• 【Stable and High-Precision Filament Transmission】 With a robust construction that withstands temperatures from –454°F to 500°F and a compressive strength of 12 MPa (1740 Psi), this PTFE tube maintains consistent, precise filament delivery even in challenging printing environments.
• 【Superior Chemical and Corrosion Resistance】Made from premium PTFE, the tube is highly resistant to acids, alkalis, and organic solvents, ensuring durability and reliability for both hobbyist and professional applications.
• 【Certified Safe for Various Applications】Made from FDA-compliant materials (FDA 21 CFR 177.1550) and rated UL-224 VW-1 for flame resistance, this PTFE tubing meets strict safety standards, making it suitable for industrial, food-related, and electronic uses.
