Heatbreak Nozzle Adaptor with Copper no Brass
I'm seeing this "cheaper" Heartbreak Adaptors on Amazon and asked myself, is this too good to be true. Then I looked into it some more and realized the difference is that the threaded tip on the Prusa model is BRASS where the cheap Amazon version is all Copper. Copper is typically softer than brass and I'd be concerned with the threads when compared to brass threads.

Anyone have experiences with this cheap Amazon copper heatbreak adaptors on MK4 or XL?
As I write this, I think I talked myself out of buying the all copper ones from Amazon, but curious on other's thoughts about them.

RE: Heatbreak Nozzle Adaptor with Copper no Brass
I ordered this copper heater for my MK4 because I had issues with the aluminium heater block in combination with the V6 adapter: https://www.aliexpress.com/item/1005006640358766.html
This also has a heatbreak with copper threads, which in this case is a very good thing because it makes sure that the thermal expansion for that thread and the copper heat block is very similar. The combination works really well and I did not have any leakages with it.
The copper threads may potentially be a problem when you disassemble the hotend very often, I agree. The easiest solution here is to buy a heat block just for use with the adapter and to never remove the adapter after assembling this thing. Given the cost for the complete set at Aliexpress, that is a totally viable option, IMHO.

Looks like the same 'kit' from Ali Express as shown on Amazon. Thanks for the tips
