Reliable and durable

After three months of heavy printing with ABS and PLA, this throat tube shows no signs of wear. The PTFE liner remains intact, ensuring consistent extrusion.

Essential spare part

Great value for money. I bought two as spares and ended up replacing my worn-out tube on my CR-10S. Prints are cleaner and jams are non-existent now.

Solid improvement

Works exactly as described. The stainless steel construction feels premium compared to the original aluminum one. Deducting one star only because shipping took longer than expected.

Good quality but tight fit

The build quality is excellent and feels very durable. It took a little extra effort to screw it in due to the tight tolerance, but once installed, print quality improved significantly.

No more heat creep

I was experiencing heat creep with my stock brass nozzle setup. This all-metal hotend component with the PTFE liner handles higher temperatures much better without deforming.
