Solid replacement part

Does exactly what it is supposed to do. The tolerance seems very precise compared to generic brands. Only giving 4 stars because shipping took a little longer than expected, but the product itself is perfect.

Perfect fit for my Ender 3 upgrade

This tube slides right into the extruder with no gaps. The inner surface is incredibly smooth, and I haven't had a single filament jam since installing it. Highly recommended for anyone upgrading from the stock blue tube.

Good quality, slightly stiff at first

The material feels very durable and high quality. It was a bit stiff to bend around the frame initially, but after running some prints, it settled into place nicely. No issues with feeding PLA or PETG.

Smooth operation guaranteed

The low friction coefficient makes a huge difference in retraction settings. My stringing has reduced significantly. This is a must-have accessory for any 3D printing enthusiast.

Excellent value for money

Comes with extra fittings which was a nice surprise. The cut ends are clean and square, making installation easy without needing special tools. Will buy again for my second printer.

Solved my clogging issues

I was experiencing frequent clogs at the heat break. Replacing the old worn-out tube with this high-temp PTFE tube completely solved the problem. Prints are consistent again.

5 FAQ

Q: How do I cut the tube to size without crushing it?

A: We recommend using a sharp razor blade or a dedicated PTFE tube cutter. Make sure the cut is perfectly perpendicular to ensure a tight seal in the push-to-connect fittings.

Q: Do I need to buy separate pneumatic connectors?

A: No, the package includes two standard PC4-M10 pneumatic fittings compatible with most MK8 style extruders, so you have everything needed for installation.

Q: What is the exact length of the tube included?

A: Each package contains one continuous piece of PTFE tube measuring exactly 1 meter in length, which can be cut to fit your specific printer setup.

Q: Is this tube compatible with ABS filament?

A: Yes, this PTFE tube can handle temperatures up to 260°C, which is suitable for ABS printing. However, ensure your hotend temperature does not exceed the tube's limit.

Q: Can this be used with a Bowden setup?

A: Absolutely. This tube is specifically designed for Bowden extruder setups where the filament needs to travel a distance between the motor and the hotend with minimal friction.
