3D Printer Capricorn PTFE Tubing Review: Is It Worth Getting?

If you are in the 3D printing field, you may have come across or heard of the Capricorn PTFE Tubing for Bowden 3D printers. This article is going to look into this product in detail and review it, so you have a better knowledge of its efficacy and functional use.

Stick around for some key details on this product and add it to your 3D printer.

When you step into the market for your printer needs, your main priority is getting better quality at an affordable price.

Going from one seller to another, you hear mixed techniques of upselling, that too, without any reviews from the users – it wastes your time and money – because, in the end, you might buy the printing accessory that doesn’t work up to the mark.


The Capricorn PTFE Bowden Tubing is one of the most well-regarded and high-end tubing models among all the others used for 3D printing. The product comes with efficient and rare features that every brand or model doesn’t provide.

Its functions make your 3D printing go as smoothly as possible. Let’s have a look at each of the tubing’s features in detail.

Tight Tolerance

The Capricorn PTFE Bowden Tubing is backed by the structure with tight tolerance. This tight tolerance makes sure that room for error is cleared. It leads the filament directly to the hotend – so there is no place between extruder and hotend for any type of mishap or spill.

This is one of the most essential features that people usually overlook. However, in Capricorn PTFE Bowden Tubing, tight tolerance is noticeably advantageous.

Moreover, the structure of the tube is also uniform, which means that it fits perfectly tight on both ends, and there is a little-to-none chance that it ever loses.

Temperature Proof

This 1-meter long PTFE Tubing is rated very highly because of its brilliant capability of withstanding the hottest temperature – it means you can print on your 3D for hours and hours without worrying about the tubing.

It’s perfect for exotic filaments – such as ABS, Nylon, Polycarbonate, etc.

Any standard PTFE tubing would melt down and cause you to experience dangerous levels of “off-gassing” if the hotend reaches the temperature over 240°C. This worsens the condition of your printer and creates irreparable damage.

This PTFE tube can go up to 300°C and allow you a safe 3D printing due to its advanced manufacturing methods.

Upgraded Pneumatic Fittings

This brilliant Capricorn PTFE Bowden Tubing comes with “metal teeth” provided within the package. These metal teeth can be referred to teeth-shaped fittings at the end of the tube, which makes it very hard to pull out a tube once it’s fitted with stainless steel fittings.

Upgraded Pneumatic Fittings allow a smooth running of the tube – and it’s better than cheap and disposable fittings and locking mechanisms provided by local brands.

With upgraded pneumatics, the extruder fitting is PC4-M6, and the fitting of the hotend is PC4-M10. In the package, the clip is also provided that noticeably increases the hotend’s precision by removing potential leakage of the tubing while the process of retracting or extruding.

A PTFE Cutter

One great advantage of the Capricorn PTFE Bowden Tubing is that it comes with a PTFE cutter. This cutter has an extra sharp razor, which is used to ensure that PTFE Tube is cut flat and smooth from both sides. Uneven cuttings can cause leakage – and not every cutter or blade can cut a PTFE tube.

So PTFE Cutter – included in the package – provides a great advantage to prevent any mishap or error, like heat creep, when feeding and retracting.

With that being said, you should keep the cutter out of sight when not using, because its extreme sharpness can be dangerous and accidental if fell into the wrong hands.

Long Length of 1 Meter

PTFE Tubes are known to be shorter but this tubing is 1-meter long. If you have some experience with 3D printing, you’d know that 1 meter is a perfectly ideal length in PTFE tubing. Therefore, it adds a vast amount to productivity.

Moreover, the long-length comes with uniform and smooth surface – texture and roughness can make it bouncy and loose.

Excellent Extrusion and Retraction

If you take a brief round of the print accessories market, you will know that many cheap printers come with sub-par PTFE accessories that are not even designed for 3D printing.

Therefore, if you use them for 3D printing, it will not only provide a worse result but also damage your expensive 3D printer. These cheap tubes give extremely poor results in extrusion and retraction.

The Capricorn PTFE Bowden Tubing is a safe choice in this matter, its highly technical and above-par parts, when combined with an excellent 3D printer, gives off a great result in extrusion and retraction.
