@Iris_IllEra@fafo@whitequark I am _very_ tempted to design and manufacture a high vacuum version of the connector side of this, too. Because yeah, there's no reason this shouldn't work as a high vacuum fitting!
@fafo since you got to 1e-2 mbar, I need to get around 1e-6mbar. So I figured that three of those should do the trick. Should I connect them in parallel or rather in series?
