Great upgrade component

Works perfectly with my CR-10 setup. The gray-black finish looks professional and matches the rest of my printer aesthetics nicely.

Solid performance

Does exactly what it is supposed to do. Printing temperatures are stable, and the flow is consistent. Would buy again if needed.

Good quality, slight thread tightness

The build quality is excellent and the bimetal design should help with heat creep. The threads were a bit tight initially but loosened up after the first heat cycle.

Essential for high-temp filaments

Using this with PETG and ABS without any issues. The bimetal construction handles the heat much better than the all-brass stock part.

Perfect fit for my Ender-3 S1

Installation was straightforward. The DLC coating seems very durable, and I haven't experienced any clogging since swapping out the stock tube. Highly recommended for upgrades.

Solved my PLA jamming issues

I was constantly getting jams in the hotend. This throat tube fixed the problem immediately. The nano coating really does seem to prevent filament from sticking inside.

5 FAQ

Q: Can I use this for printing TPU?

A: Absolutely. The smooth interior provided by the DLC coating makes this tube excellent for flexible filaments like TPU, as it minimizes resistance during feeding.

Q: Does this come with thermal paste?

A: Yes, the package includes a small amount of high-quality thermal compound to ensure optimal heat transfer between the throat tube and the heat block.

Q: What is the return policy if it doesn't fit?

A: We offer a 30-day return window for unused items in original packaging. Please verify your printer model compatibility before installation to ensure the best fit.

Q: Is this compatible with the original Ender-3 V2?

A: This specific model is designed for the Sprite extruder found on the Ender-3 S1, CR-10, and CR-6 SE. It may not fit the standard Ender-3 V2 without modification.

Q: What is the benefit of the DLC Nano coating?

A: The DLC (Diamond-Like Carbon) Nano coating reduces friction inside the tube, preventing filament from sticking and significantly reducing the risk of clogs, especially with flexible materials.
