Newwish 3 Meters PFA Tube Kit ID 2mm X OD 4mm,PTFE Teflon Bowden Clear for 1.75mm Filament,3D Printer Transparent Tubing with PC4-M6 Connector X5,PC4-M10 Pneumatic Fittings X5,Bowden Collet X5.

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. 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 Detail Printing: ID 2mm, Ideal for users who prioritize print quality and fine details. A smaller clearance helps reduce filament wobble, ensuring more stable filament feeding in high-resolution prints with fine details. Compatible with all 1.75 mm filaments, especially suitable for printing flexible filaments (TPU, TPE). Pneumatic Connectors: PC4-M6 with M6/3mm threads, ID 4.2mm; PC4-M10 with M10/6mm threads, ID 4.2mm; Bowden coupler: ID 4.2mm. All of the above connectors are compatible with 4mm outer diameter tube, stable and durable, easy to replace, , and high compatibility – this will become a practical spare part or replacement part for your 3D printer extruder and hotend. Note: If you’re aiming for high-flow, high-speed printing, especially with longer Bowden feeding setups, a 2mm ID tube may increase feeding resistance. In these cases, a 2.5mm ID tube is a more balanced choice for smoother feeding and more reliable performance.
