    • Excellent PTFE tube and fittings — perfect for smooth 3D printing!
I purchased this SIQUK PTFE tubing and fitting set for my 3D printer, and I’m genuinely impressed with the quality. The tube itself feels durable and has a very smooth inner surface, which made filament feeding noticeably more consistent, especially with PLA and PETG 1.75mm filament. The included PC4-M6 and PC4-M10 fittings fit perfectly on my printer and hold the tube securely without any slipping. Installation was quick and straightforward — it took only a few minutes to swap out my old worn tube and connectors. Since replacing the original parts with this set, I’ve had fewer clogs and much smoother extrusion overall. Print quality has improved, and filament loading/unloading is much easier now. I also appreciate that the package includes multiple fittings, which is great to have as backups for future maintenance. For the price, this is an excellent value and a must-have spare parts kit for anyone with a 3D printer. Highly recommend! ... show more

    • This is the one!
Worked well on my Ender 3. Standard 4mm tube fitting with both standard thread sizes found on most 3d printers. The tube is standard quality, nice touch.

    • Good set at reasonable price
Good deal with a good fit to mod my Bambu printer. Easy installation and works great. No issues so far. Just don't overtighten and all will be good and parts will last.

    • Work great until they don't.
The tubing is fine, the small brass colored connector works well, until you try to take the tube out. The push ring doesn't work, then the teeth break loose & won't hold the tube anymore. Good thing there's so many in the package, you'll need them.

    • good value, small tubes
good overall, however it is smaller than the recommended 2.5mm ID 4mm OD for bambu+AMS setups. If you are looking to replace your PTFE on any bambu labs printers know that you will have AMS feed issues

    • Awesome for 3D Printing Upgrades
I have used these fittings to add various capabilities to my 3D printing setup. They are well made, easy to use and exactly to spec. The fittings grab the PTFE tubing very securely but are still easy to release when you press down on the fitting. The included PTFE tubes work very well even though they are a bit stiff from being rolled up so long. Came well packaged, the tubes were all zip tied in rolls and secured with no damage. The fittings came in little plastic baggies that make them easy to keep track of for the future. ... show more

    • Great for filament dry boxes.
Worked perfect for making 3D print filament dry boxes. Holds PTFE well.

    • BUYER BEWARE: this tubing and connectors are NOT for 3D printing use!
Warning. The tubing ID is far too small to handle 1.75mm filament. Also, while the connectors will fit regular PTFE tubing with an actual 2mm ID, nthe brass fittings have a lip on the inside on the threaded side that makes it almost impossible to feel filament through. The nickle plated fittings are much wider and should fit filament without issue. However, there are very few applications for those fittings. So BUYER BEWARE! THE FIT IS NOT APPROPRIATE FOR 3D FILAMENT! That being said, the sizing of the brass fittings is great. Just only if you're using it for anything other than 3D printing. The title does mention pneumatic applications, but I feel it should have indicated that this is not for 3D printing. I'll add a picture that shows the hexagonal "lip" inside the threaded end of the fittings that the filament catches on. It's a shame, really...as these are not poorly made. ... show more
