  Threadlocker is often used in automotive applications, like engines, but an engine rarely exceeds much above 110 °C. Looking at the datasheet for 222, it’s rated for 150 °C, but it does look like it loses strength as it warms up and it also starts to break down above 120 °C.

  I can’t see it hurting, but it might not be as long term a fix as I had hoped. If it comes apart again, I’ll have to try 272. It’s rated for “up to” 232 °C.

  I am very curious how hot the heat break actually gets.

    Interesting, if you’re using it for the cooler part of the heat break then it should be a lot cooler since that’s what the heat break does.

    It might not hurt, but if I had to imagine a scenario, I’d say it could break down and create carbon deposits that could act like graphite powder and lubricate the screws. I guess time will tell ¯\_(ツ)_/¯

      That would be a truly amusing outcome, lol. You’re right - time will tell. But thankfully at least I’ll know what to look out for this time around.

    Red loctite on fastners that small has a recipe for being a bad time if it sets up proprly, I find some of the small screws around the hotend can already be prone to stripping due to things like plastic buildup thats hard to remove.

    At least on the dragon, theres a sizeable gap between the inner and outer portions of the heatbreak and some distance between the block and the heatbreak, I’d be surprised if the threads get hot enough to worry about even without the hotend fan.

      Thanks for the intel! Here’s hoping that the purple holds.
