[labnetwork] Anti-seize coatings for VCR threads

[Dan P. Woodie]

Most Excellent Lab Network Community,

We have parts for our ALD tool that returned from cleaning with the silver anti-galling layer on the VCR nuts severely damaged. The concern is that these are the heated lines that feed the ALD chamber and therefore, after being tightened for 6+ months before the next cleaning, the heated stainless-steel surfaces will seize up and we won't be able to remove the nut. Is anyone aware of an anti-seize coating or similar options that we can apply to these threads to be able to use this damaged manifold? Given that the VCR threads are not in the flow path, we are hoping to be able to continue use the manifold, as it is quite expensive to replace.

Thanks for any advice the community can share.

Dan
