Premium Bowden Tube Upgrade for Smoother Filament Feeding

The Creality Capricorn Bowden PTFE Tubing is a drop-in upgrade that replaces the stock white PTFE tube on Bowden-style 3D printers. Capricorn's tighter inner diameter (1.9 mm vs 2.0 mm standard) reduces filament play, improving retraction performance, reducing stringing, and enabling better prints with flexible filaments like TPU.

Why upgrade to Capricorn?

  • Tighter tolerances: 1.9 mm ID vs 2.0 mm stock — less filament wobble
  • Lower friction: Premium PTFE reduces feed resistance
  • Higher temp rating: Handles up to ~260 °C before degradation
  • Better retractions: Reduces stringing and oozing
  • Flexible filament friendly: Tighter bore prevents TPU from buckling

Compatible printers

Fits Creality Ender 3/V2/Pro, CR-10 series, CR-6 SE, and most Bowden-style printers using 1.75 mm filament with a standard 4 mm OD / 2 mm ID tube.

Frequently Asked Questions

Will this help with stringing? Yes. The tighter bore improves retraction responsiveness, which is the main cause of stringing.
Is it hard to install? No. Cut to length, push into the fittings. It's a 5-minute swap.
