Newwish PFA Tube ID 2.5mm X OD 4mm,PTFE Teflon Bowden Clear Transparent for 1.75mm Filament 3D Printer Bambu Lab A1/A1 Mini/P1P/P1S/X1C/X1E/AMS/K1/K1 Max/K1C/Ender 3 V3/V3 Plus Tubing.(3 Meters)

PFA Tube: This is our latest high-transparency, heat-resistant tube. We use premium materials and a slower production speed to deliver higher clarity and smaller tolerances. The smooth inner wall reduces filament friction for more consistent feeding across a wide range of materials. Specification: High transparency PFA Tube, heat-resistant (260℃+), ID 2.5mm X OD 4mm for 1.75mm filament, It can effectively replace PTFE tubing, offering comparable heat resistance, and is suitable for use in high-temperature areas of the filament path, including near the hotend. High Transparent: This highly transparent tube allows real-time monitoring of filament movement, making it easier to quickly detect blockages or anomalies. This significantly reduces downtime and improves the reliability of your prints. An ideal choice to fine-tune your settings and optimize the calibration of your 3D printer. High Stability: ID 2.5mm, The inner diameter is moderately increased to reduce feeding resistance while maintaining good print accuracy and stable filament control. Suitable for high-flow and high-speed printing. Compatible with all 1.75mm filaments, suitable for most 3D printing needs. Balanced Performance: This balanced design helps reduce common printing issues such as extruder slipping/filament grinding, inconsistent extrusion, and clogging—especially in longer Bowden feeding setups or during high-flow, high-speed printing.
