Creality Upgrade 3D Printer Kit with Capricorn Premium XS Bowden Tubing 1M， PTFE Teflon Tube Cutter, Pneumatic Fittings and MK8 Socks and Extra Nozzles for Ender 3/3 Pro/5/Voxelab Aquila

Works great compared to stock

A++++

Its a Capricorn PTFE bowden tube. It does what you expect. The little clip tube cutter is nice, and the silicone hot end cover thing is also nice.

PC4-M10 Pneumatic Fitting is recessed on the inside and thin walled. When you install this on the extruder it makes it near impossible to feed new filament through it. The tip of the filament will just hit the edge of the lip left on the inside. You can see the new fitting in the photo (top) compared to the old fitting I luckily still had (bottom).

The Capricorn tubing is a great upgrade, especially if you’re running filaments that require high temps. The silicone socks do not fit over my heater block which is the main reason I bought this set.

I got this more for the hardware then the actual tube. Everything is working fine. There might be a very slight improvement in print quality.

It fixed the problem I had when printing pla and petg on ender 5. Printing quality improved. The tube is good, the filament material doesnt get stocked and feet well @ any1.75 mm. Support high temperature @240C when I print petg. Good quality money ...

Having new bowden connectors, silicon sock, cutter, and new nozzle in one well priced kit is great. Was able to replace the stock (janky) bowden connectors, PTFE tube and worn out nozzle in one go. And replace the fiberglass insulation taped on with kapton tape with the silicon boot. Very happy with purchase. Took about 10 minutes.

Really improves the printer

The tube inner diameter should be 2.0mm with a .05mm allowable variation per the manufacturer. The ends of the tube had variation in the inner diameter and was about 1.8mm at one end making it so the 1.75mm pla could not pass through, resulting in inability to print.
