Works well but shipping was slow
The product itself is excellent and fits my printer without modification. However, the delivery took longer than expected.

Precision machining evident
You can tell this was machined with care. The internal bore is smooth which helps filament flow significantly. Will buy again.

Solved my heat creep issues
Switching to this longer throat tube completely eliminated my heat creep problems when printing PLA. Highly recommended upgrade.

Essential for flexible materials
If you print TPU or other flexible filaments, this long throat is a must-have. It provides enough distance to prevent softening before the nozzle.

Good quality, slightly tight thread
The stainless steel feels very durable. The M6 thread was a bit tight initially but loosened up after a few uses. Great value.

Perfect fit for my MK8 setup
The threading is precise and the length options allowed me to customize my hotend perfectly. No more clogs with flexible filaments.
Q: Is the 50mm version compatible with standard E3D V6 hotends?
A: This tube is specifically designed for Makerbot MK8 extruders. While it shares M6 threading, the length and shoulder design may not fit E3D V6 blocks without modification.
Q: What is the maximum temperature this tube can withstand?
A: Made from high-grade stainless steel, it can safely withstand temperatures up to 300°C, suitable for most common filaments including ABS and Nylon.
Q: Does this come with a brass nozzle included?
A: No, this listing is for the long throat tube only. The nozzle is sold separately.
Q: Can I use this for printing carbon fiber filled PLA?
A: Yes, the stainless steel construction is durable enough for abrasive filaments like carbon fiber filled PLA, though we recommend using a hardened steel nozzle as well.
Q: How do I choose between 30mm, 40mm, and 50mm?
A: Choose based on your hotend block height and cooling requirements. Longer tubes (40mm/50mm) offer better heat isolation for flexible filaments, while 30mm is standard for rigid materials.
