Essential upgrade

Great value for money. The M6x40 size was exactly what I needed for my custom cooling block design.

Robust construction

Very solid piece of hardware. The polished interior helps filament glide through without resistance. Will buy again.

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.

Solved my retraction issues

Switching to this longer throat tube significantly improved my print quality with PLA. Highly recommend for anyone modifying their extruder.

Good quality, slight installation tightness

The steel feels durable and high quality. It was a bit tight to screw in initially, but once seated, it works flawlessly.

Works well after calibration

Had to recalibrate my E-steps after installation, but the print results are much smoother now. Good product.

5 FAQ

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

A: The stainless steel construction can safely handle continuous operation up to 300°C, which covers most standard printing materials including ABS and Nylon.

Q: Is this compatible with E3D V6 hotends?

A: This specific tube is designed for Makerbot MK8 hotends. While dimensions may seem similar, we recommend checking your specific thread pitch and seating depth before attempting installation on E3D systems.

Q: Do I need PTFE tape for installation?

A: Generally, no. The M6 threads are designed to seal metal-to-metal. However, if you notice minor leaks, a small amount of high-temperature thread sealant can be used, but avoid getting any inside the bore.

Q: Which length should I choose for printing TPU?

A: For flexible filaments like TPU, the 50mm option is often preferred as it provides a longer thermal break, reducing the chance of the filament softening too early in the path.

Q: Does this come with a heat sink or just the tube?

A: This listing is for the long throat tube only. The heat sink and heater block are not included.
