Click here for installation directions. Does NOT fit the “NEO” series if you have the silver color hotend. This only works with the standard red-colored style hotend (and CR-10 V2/V3 Stock silver hotend) as shown below and in the product pictures. If you hotend does not match the pictures below then measure your existing heatbreak to compare to the measurements below to verify it if will fit. We are not responsible for improper fitment because you did not check your existing heatbreak .

  • Fits all machines listed below
    • Ender 2/2 Pro/3/3 MAX/3 V2/4/5/5 Plus/6
    • CR-10 (Standard, Mini, S4, S5)
    • CR-10S (Standard, Mini, S4, S5)
    • CR-10 V2 and V3
    • Sovol SV01/SV03
    • Sunlu S8 
    • Sunlu S8 Pro
  • Smooth internal bore
  • Transfers much less heat than steel or PTFE Style Heatbreaks for lower heat transferred to upper cold end heatsink
  • Made from TC4 Titanium Alloy (lower) and Copper (upper)
  • Heatbreaks are delicate parts.
    • Never tighten your nozzle without holding the heater block with pliers. Doing it without can break the transition zone (the thinnest part).
    • Nozzle crashes can also bend the heatbreak. If your heatbreak is bent in a nozzle crash slowly try to bend it back to the original position.
    • Our warranty does not cover damage to the heatbreak from over-tightening or nozzle crashes, only defects in the product itself.
  • Product Dimensions:
    • Inner Diameters: 4mm at the top, 1.88mm about 5mm deep. This holds the PTFE tube in the top and does not allow it to go all the way through.
    • Outer Diameters: 7mm (smooth section), 2.6mm (throat), 6mm (threading)
    • Lengths: 20mm (smooth section), 2mm (throat), 5.5mm (threading), 27.5mm (overall)

Tips for Using This Heatbreak

Installation directions: Heatbreak Installation Information

Oil it – We recommend if you are getting jamming with PLA (this can happen with ALL METAL heatbreaks from any manufacturer) to print a filament oiler. Like this one: Stuff it with a sponge or fiber then lightly wet with CANOLA oil. This will oil the filament path and keep the PLA from sticking to the heatbreak on a longer retract. After using this for about a month or two your heatbreak should have a nice “seasoning” on the inside and use of an oiler will be needed less or not at all.

Lower Retraction – Stick to under 3mm retractions. All metals will need less retraction than a PTFE lined hotend. 25-50mm/s depending on your machine setup. Wipe is recommended (2-5mm).

Thermal Paste (Optional, but recommended) – When installing the heartbreak you can apply thermal paste/grease (like what is used on computer CPUs) to the outside that inserts into the heatsink before installation. This will improve thermal transfer from the heatbreak to the heatsink.

    I have ordered many parts from TH3D and this one didn’t disappoint. I fit into my Sovol SV05 nicely and I didn’t even notice a difference. Very satisfied with the performance.

    Works great.

  3. Michael V. (verified owner)

    Paired with direct drive, excellent combo

    I have been using this for a couple weeks now, and I would say it is one of the better upgrades I have done to my Ender 3 pro. Almost every time I would print something with PETG or a higher temp filament, I would run in to clogging issues after. I even did the “upgrade” where you use a short piece of Capricorn tubing in the hot end, instead of the factory white tubing. This worked better than the stock setup, but still not well. I installed this heatbreak and I haven’t had an issue since. I can go back and forth between any combinations of filament types, and not have any issue. I did install an oiler/dust remover as recommended, and I honestly don’t know if it helped or not, but it sure seems like it is all working great. Only possible issue, is that the pei build plate isn’t sticking quite as well lately, and I am guessing that is from oil from the filament being left on the plate.

    Great value and comparable in performance to Slice Engineering product. Currently running well in my Creality CR-10 V2 w/ Titan Extruder.

    Working great so far. Using this on a CR-10 V3 with creality’s knockoff V6 that came with the machine. I did use some thermal grease when putting it into the radiator block.

    Rocking one of these on my CR10 and my Ender 3, I’ve already printed ABS/PETG/TPU and PLA with no jams or any other issues.
