Creality Capricorn Low-Friction PTFE Tubing, 4mm OD x 1.9mm ID, Blue

High-Performance Feeding for Precision Printing

Upgrade your 3D printer’s extrusion system with the Creality Capricorn Premium PTFE Tubing. Developed specifically for 1.75mm filaments, this tubing features a highly constrained internal diameter that significantly reduces "slop" or play inside the Bowden tube. This results in more accurate retractions, less stringing, and the ability to print flexible filaments with greater reliability.

Key Features

• Ultra-Low Friction Additives: Infused with a proprietary blend of high-performance additives that reduce the friction coefficient, allowing the filament to glide through the tube with minimal resistance for smoother extrusion.
• High Precision Internal Diameter (1.9mm ± 0.05mm): The tight 1.9mm inner diameter is significantly narrower than standard 2.0mm tubing. This prevents the filament from "snaking" inside the tube, ensuring instantaneous response during retractions.
• Enhanced Heat Resistance: Capable of withstanding higher temperatures than standard PTFE. It is safer for printing at elevated temperatures (up to 300°C), reducing the risk of the tube off-gassing or deforming at the hotend interface.
• Perfect for Flexible Filaments: The tight constraints make it much easier to print TPU and other flexible materials by preventing the filament from buckling between the extruder and the nozzle.
• Vibrant Blue Aesthetic: The signature "Capricorn Blue" is not just for looks; it is a mark of authentic, high-density PTFE material designed for the rigors of 3D printing.
• Universal Compatibility: 4mm outer diameter makes it a drop-in replacement for almost all FDM 3D printers using 1.75mm filament.

Elevate Your 3D Printing Game

The Capricorn tubing is the single most cost-effective upgrade you can make to a Bowden-style 3D printer. By tightening the filament path, you gain better control over flow rates and pressure advance settings, leading to cleaner corners, sharper details, and a significant reduction in post-processing time.
