1 Meter Retail package - XS Low Friction 1.75mm Bowden Capricorn Tubing
OD- 4.0mm ID - 1.9mm Two meters of XS PTFE Capricorn 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 on the market and genuine from the USA.
Guaranteed to always be the right diameter, and perfectly round. Print flexible filaments without the binding up that happens with over-diameter tubes.

♠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. §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. 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. ♥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. More information please see the Capricorn Page here.
