Great for custom hotends

We use these for several custom printer builds in our lab. The consistency between units is impressive, making assembly very predictable.

Solved my clogging issues

I upgraded to this longer throat tube to improve heat isolation, and it worked like a charm. No more clogs with PLA or PETG filament.

Good quality, slightly long shipping

The tube itself is excellent quality and matches the specifications perfectly. My only complaint is that shipping took a bit longer than expected, but the product is worth the wait.

Solid component

Does exactly what it is supposed to do. The finish is clean, and there are no burrs on the threads. Would buy again if I need spares.

Perfect fit for my MK8 setup

The threading is precise and it screwed in smoothly without any cross-threading issues. The stainless steel feels durable and should handle high temperatures well.

Essential upgrade

If you are running abrasive filaments or just want better thermal performance, this long throat tube is a must-have accessory for the MK8 system.

5 FAQ

Q: Does the 50mm version fit in a standard Creality CR-10?

A: The CR-10 typically uses a different throat design. This item is optimized for MK8 style extruders. Please verify your printer's hotend model before ordering the 50mm length.

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

A: The stainless steel construction allows for continuous operation up to 300°C, which covers most standard filaments including ABS, PLA, and PETG.

Q: Is this compatible with E3D V6 hotends?

A: This tube is specifically designed for Makerbot MK8 nozzles with M6 threading. While some V6 clones use M6, we recommend checking your specific heater block dimensions before purchasing.

Q: Are replacement washers included in the package?

A: The package includes only the throat tube. We recommend reusing your existing silicone sock and washers or purchasing a maintenance kit separately if needed.

Q: Do I need PTFE tubing inside this metal throat?

A: No, this is an all-metal throat tube designed to eliminate the need for PTFE liners inside the heat zone, allowing for higher temperature printing.
