Can't install new hot end

Friends,

It's been a while since I've been here. I think I got my username right, but an antivirus program wiped my identities and passwords. In the mean time, I got the Micro Swiss MK8 wear resistant hot end upgrade recommended by a member -- a barrier tube and nozzle that's supposedly super-slippery and compatible with printing at high temps such as with nylon and clog-resistant..

The time came to install it. Turns out, the heat break, heater/thermistor block and nozzle were irretrievably fused together.So I went to Folger in hopes I could buy a new set. They've been sold out for weeks.

I sent them an email about future availability and got no response. Has anyone heard any rumors about this situation? (Surely they have enough in stock to sell FT-5 kits.) My hopes are wearing thin.

Is there a chance another manufacturer/printer has a hot end assembly that's compatible with the FT-5? Recommendations will be welcome.

To keep this from happening again, I am considering using something on the threads like Loctite 51147 C5-A Copper Based Anti-Seize, which is rated up to 1800F. Is this a good idea?

Thanks!

I am not at that familiar with the Micro Swiss components, but assuming that it is all M6 threaded below the motor block you can just purchase similar parts to the originals on eBay inexpensively.
It claims to be MK8 compatible and from what I can see in the link it appears that it should work.

Such as this-

Or this-

(Just use your 24 volt heater instead of the 12 volt one)

I am sure that FT will return to life once this pandemic abates, but in the meantime there are other sources for these types of things.

Be a bit careful with the anti-seize, don't get it into the bore.
I use heat sink grease instead.
