Essential for high-temp materials

I use this with ABS and the extended length provides better temperature gradient control. Very satisfied with the build quality and price point.

Good quality but check your lengths

Solid construction and smooth interior. I ordered the 50mm version which was slightly longer than I needed for my specific carriage, but it works after minor adjustment. Just measure twice before buying.

Fast shipping and great part

Arrived quickly and well-packaged. The M6 threads engage smoothly without cross-threading. Highly recommend for anyone upgrading their Makerbot style extruder.

Perfect fit for my custom setup

The M6x40mm tube fits perfectly into my modified hotend. The threading is precise and the stainless steel quality feels durable. Great for extending the heat break zone.

Excellent thermal isolation

Using the long throat tube has significantly reduced heat creep issues with my PLA prints. The extra length helps keep the filament cool before it reaches the melt zone.

Works as described

No complaints here. It's a simple metal tube that does exactly what it says. The finish is clean and there are no burrs inside to catch filament.

5 FAQ

Q: Can I use this for printing flexible filaments like TPU?

A: Yes, the smooth inner bore helps reduce friction, which is beneficial for flexible filaments. However, ensure your retraction settings are tuned correctly for the increased distance.

Q: Is the 30mm version short enough for a stock Makerbot Replicator 2?

A: The stock configuration typically uses a shorter heat break. The 30mm version may require adjustments to your hotend assembly or cooling fan positioning. We recommend measuring your current setup before ordering.

Q: What is the maximum temperature this tube can withstand?

A: The high-grade stainless steel construction can safely withstand temperatures up to 300°C, making it suitable for most common filaments including PLA, ABS, and PETG.

Q: Will this fit a standard E3D V6 hotend?

A: This tube is specifically designed for the Makerbot MK8 nozzle system with M6 threading. While dimensions may seem similar, we cannot guarantee compatibility with E3D V6 systems without modification.

Q: Does the package include a nozzle or just the throat tube?

A: The package includes only the long throat tube. The nozzle must be purchased separately if you need a replacement.
