I would say any high temperature lube - MoS2 based or graphite based, dry one. But I suspect particulate contamination from any external stuff may be a concern. </div>

Is there an option to re-weld the gland with a new nut? Or if I remember correctly, Swagelok had some options for a split male nut and a joint F-F through nut to replace a female nut without removal.</div>

<div>Hi Dan,</div>
<div><br>
</div>
<div>I've had good luck with Loctite 37617, silver-based antisieze.</div>
<div><br>

<div><a href="https://www.amazon.com/Loctite-37617-6PK-Silver-Grade-Anti-Seize-Lubricant/dp/B0053ZS1Z8?th=1">https://www.amazon.com/Loctite-37617-6PK-Silver-Grade-Anti-Seize-Lubricant/dp/B0053ZS1Z8?th=1</a></div>
<div><br>
</div>
<div>I only use it on non-vacuum wetted surfaces, typically conflat flange bolts, so I cannot comment on outgassing, but I would have no aversion to applying it to a VCR thread. The glue-stick style applicator is wonderfully convenient.</div>
</div>
<div><br>
</div>
<div>Good luck!</div>

<p class="x_MsoNormal"><span style="font-size:11pt">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.<u></u><u></u></span></p>
