Capricorn XS Series Premium PTFE Bowden Tube

The XS Series Premium PTFE Bowden tube is sold in lengths of 50cm. For longer lengths increase quantity for one continuous section. For example quantity of 2 would equate to 100cm

Capricorn XS Series Premium PTFE Bowden Tube

Capricorn XS Series Premium PTFE Bowden Tube is made from the highest quality PTFE designed for 1.75mm filaments. Capricorns secret blend of high lubricity additives turns it a deep blue color. This is hands down the best PTFE bowden tube you can buy. It is guaranteed to be the right diameter and perfectly round.

High Lubricity Additives
Make our XS Series Premium PTFE Bowden Tube the lowest friction Bowden tubing on the market. These are not a coating but are inside the PTFE. Less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear, and tear on the extruder, and less clogging when printing chunky filaments such as some wood fills or iron fills.

Lower retraction
Means time saved every time the extruder retracts. Over the course of a print, a few milliseconds here and a few there add up to a lot of time saved.

1.9mm ± 0.05mm Inner Diameter
The XS Series Premium PTFE Bowden Tube offers a tighter inner diameter tolerance than traditional tubing reduces the “wiggle room,” or buckling, inside the tube, allowing you to print flexible filaments even on the longest Bowden systems.

High-Temperature Resistance
The high-temperature additive improves the thermal properties of the PTFE, allowing it to print at higher temperatures for longer duty cycles. Our XS Series Premium PTFE Bowden Tube will operate at even higher temperatures than our TL.

Inside Diameter
1.9mm

Outside Diameter
4.0mm

Safety Precautions

PTFE is a fluoropolymer, which exists in a state of matter known as a “glass.” This means it does not “melt,” like an ice cube, but rather slowly gets softer and softer as it gets warmer. Eventually, it will either become a liquid or catch fire. Between room temperature and catching fire, all polymers emit tiny amounts of harmful gasses, known as “off-gassing.” The hotter they get, the more they will emit.

Because our PTFE tends to have better temperature resistance (meaning it stays firmer at higher temperatures before significant deformation) than lower quality PTFE tubes, a number of users have reported success using it “inside the hot end.” This is not something you should do willy-nilly. Just because it works, doesn’t mean there aren’t precautions to be taken. If you use PTFE, or any polymer for that matter, inside the hot end or anywhere excessive temperatures may be experienced, you will potentially create harmful off-gassing. Not only that, but the polymer you are extruding may be creating harmful gasses as well.

We strongly recommend running your 3D printer in a well-ventilated area, away from children and pets.
In a classroom environment, we encourage printing with PLA and staying away from higher temperature materials, whether you use our Bowden tubing or not. Always have adult supervision when operating a 3D printer. Keep razor-sharp Bowden tubing cutters out of reach of children.

Have fun, and stay safe out there!
