DESCRIPTION

One Meter of our flagship PTFE Tubing, enhanced with a proprietary blend of high performance additives. 1.9mm inner, 4mm outer diameter for 1.75mm filaments.
This is, hands down, the single best PTFE Bowden tubing you can buy for your home 3D printer.

Guaranteed to always be the right diameter, and perfectly round. Print flexible filaments without the binding up that happens with over-diameter tubes.

Each meter of tubing comes with one Capricorn sticker to decorate your printer.

EXTRA SPECIFICATIONS

  • Additives: Blue Color and Secret High Lubricity Additive Mixture
  • Best For Chunky Filaments: YES
  • Best For Flexible Filaments: YES
  • Can See Through: NO
  • Pulling Friction: 0.8
    • Pulling Friction is calculated as the average force required to pull 1.2 meters of 1.75mm PLA filament through 1 meter of tubing at a constant speed, relative to 1 meter of cheap white reference tubing. Note that although we observed the friction of the TL series to be about the same or even slightly lower than our XS series, it also has a larger internal diameter.
  • Color: Dark Blue
  • Density (kg/m3): 2300 +/-100
  • Hardness: 60-65
  • Inner Diameter (mm): 1.90 +/- 0.05
  • Linear Thermal Expansion at 250°C: 2.2-3.3%
  • Material: Highest Quality Pure Virgin PTFE
  • Melting Point (°C): up to 340
    • Temperatures were approximated by heating samples of all tubing simultaneously, observing how quickly each one began to deform. Printer failures may happen at significantly lower temperatures.
  • Outer Diameter: 3.95 +/- 0.05
  • Roundness (ϵ): < 0.1
  • Stiffness: Medium High
    • Other Bowden tubes may vary significantly in stiffness, depending on the material from which they're made. Our tubing generally tends to be more flexible than most, with the TL being more flexible than XS.
  • Thermal Conductivity (W/m-k): 0.25
  • Wear Rate (gm/s): 0.01
  • Young's Modulus (GPa): 0.53
    • Young's Modulus (YM) is the measure of elasticity of the material. Our XS Series additives give the PTFE a slightly greater YM than the TL Series.

FEATURES

Capricorn XS Series PTFE Tubing VS Original PTFE Tubing

1.9mm ± 0.05mm Inner Diameter Reduces the "wiggle room," or buckling, inside the tube, allowing you to print flexible filaments even on the longest Bowden systems.
