Great value for money
Compared to branded alternatives, this offers the same performance at a fraction of the cost. The 35mm length is ideal for my custom rig.

Works but requires patience
It works as described, but installation took longer than expected because I had to realign my heatsink. Make sure you have thermal paste ready.

Excellent for flexible filaments
I use this primarily for TPU prints. The extra length and smooth liner prevent jamming significantly better than the stock short tube.

Solid upgrade component
Precise machining on the threads. No gaps between the tube and the heat break. Highly recommended for anyone modifying their extruder.

Good quality but tight fit
The stainless steel feels very durable. It was a bit tight going into the heat block at first, but after some careful tightening, it seated well.

Perfect fit for my direct drive setup
This extended throat tube solved my heat creep issues immediately. The M6 threading matched my hotend perfectly, and the PTFE lining is smooth.
Q: Does this come with thermal compound?
A: Yes, each package includes a small sachet of high-quality thermal compound to ensure optimal heat transfer during installation.
Q: Can I use this with 2.85mm filament?
A: No, this throat tube has an inner diameter optimized for 1.75mm filament. Using 2.85mm filament will cause immediate jams.
Q: How do I remove the old tube if it's stuck?
A: Heat the hotend to about 100°C to soften any residual plastic or thread locker, then use an appropriate wrench to unscrew it gently.
Q: What is the maximum temperature rating?
A: The PTFE liner is rated up to 260°C. We do not recommend exceeding this temperature to avoid degradation of the lining.
Q: Is this compatible with E3D V6 hotends?
A: Yes, as long as your V6 setup uses an M6 threaded connection and you are running a direct drive configuration, this 35mm tube should fit.
