I agree with Bob. Conflat seals are good for very impressive vacuums. ________________________________ From: Bob Higgins <rj.bob.higg...@gmail.com> Sent: Friday, June 28, 2019 3:58 PM To: vortex-l@eskimo.com Subject: [Vo]: Seals
Hi Dave, This looks like standard conflat UHV gear to me. The typical gasket used for conflats is a fairly thick copper ring that is sealed by compression between knife edges turned into the conflat faces. In absence of a description of a special gasket material, I would presume it is the standard copper gasket.

One question I have is what material is used as a gasket between the end flanges and the SS reaction chamber? It is hard to believe that nothing is required to prevent leaks.

I answered my own question. Of course the type of material is very critical for anyone wanting to replicate the experiment.
