2M PTFE Teflon Tube for 3D Printer - 1.75mm Filament, 4mm OD X 2mm ID Clear High-Temperature Resistance Flexible Extruder Tubing

Great fits perfectly

Used for extruder rebuilds on son's 3D printer

I’m fairly new to 3D printing. If you are replacing your hot end on your Tronxy this is perfect! There is a clip on one wire that plugs right into the circuit board, the other wire is pinched to the board with screws (in case you were wondering.. no soldering required!) anytime I ever googled that it was never really clear, anyway..My only complaint is that the heat break tube was too short for my Gemini S. Which is really an invalid complaint because in their defense it doesn’t say ‘ for Gemini S’ in the tile or description, I just assumed all the parts would be interchangeable. I had to order the tube from the Tronxy website and wait 20 days for the part to arrive but when it did everything fit perfectly together and works like a dream.

These are really good for many things,However be very careful, they can be broken easily as they are really really thin. Be careful handling them.

Rerouted my filament feeder tube with this. It was the perfect fit and is holding up well.

This appears to exactly match the extruder that was on my Late 2021 X5SA Pro. I was thinking I might need to replace the whole hotend, but I really just needed one of the nozzles this thing came with for now. Fit perfect on my existing hot end. The rest of it and spare nozzles are good replacement parts if I need em.To be clear, it doesn't appear to be an update for the Pro models, just the one it came with.

The drill bits are to fragile and break off easy in the nozzles. I have 2 nozzle's that I need to clean out.
