Easy to install for beginners

I was worried about installing this myself, but it screwed right in without any issues. My prints are coming out much smoother now.

Standard specs, works well

Dimensions match the description exactly (M6x30mm). The PTFE lining looks durable. Took off one star only because the packaging was a bit flimsy.

Solved my extrusion problems

My old heat break was worn out causing inconsistent extrusion. Replacing it with these restored my print quality immediately. Highly recommended.

Essential spare part

Every 3D printer owner should have a few of these in stock. They are inexpensive and easy to swap out when wear occurs. Great product.

Perfect fit for my Makerbot

These heat breaks fit perfectly into my MK8 setup. The threading is smooth and the PTFE tube sits flush inside. No more clogging issues!

Good quality, fast shipping

Solid construction and good value for a 5-pack. One unit had a slightly rough thread but the other four worked flawlessly. Would buy again.

5 FAQ

Q: Is this compatible with the Creality Ender 3 V2?

A: Yes, this M6x30mm heat break is fully compatible with the Ender 3 V2 as it uses a standard MK8 style hotend.

Q: What is the maximum temperature these can withstand?

A: The PTFE liner is rated for continuous use up to 240°C. For higher temperature filaments like ABS or Nylon, we recommend all-metal heat breaks.

Q: Does the package include thermal paste?

A: No, this package contains only the heat break tubes. Thermal paste is sold separately, though many users reuse existing paste during installation.

Q: Can I use this with PLA and PETG filaments?

A: Absolutely! This heat break is ideal for PLA, PETG, and TPU filaments which print well within the 240°C limit.

Q: How long is the PTFE tube section inside?

A: The internal PTFE liner extends approximately 20mm into the stainless steel body, ensuring a smooth path for the filament.
