Hi Jens,
I actually mean system with metal to metal seals, sorry ;-) But even these
parts with KF/NW flanges are expensive..
I am going to build one from glass, all parts are easy to collect and I
will learn just glassblowing, what will be useful for nixies too..

Hi,
John's manifold is amazing, there is so much thought in every single
detail. Still speechless.
if You want to build a metal manifold based on the KF/NW flanges, it would
be very expensive, these components are used in 10^-9 torr system..
That sounds a little too much; DN16 systems use rubber o-rings:

I do not think you will achieve 10^-9 Torr with these.
Do you perhaps mean the CF system where you have metal-to-metal seals?
Anyway, I am not craftsman enough to build myself a fancy manifold like
John, so that is why I asked for possible sources of a needle valve of the
like I posted.

Hi folks,
I am currently working on my manifold (actually, at the moment it is
less than a monofold), and I use the DN16 flange system. The best vacuum
that I can achieve is 10^-2 mbar at the moment.
Currently I am trying to find a nice needle valve for that system, just
like this one here:
http://www.ld-didactic.de/index.php?id=ld-artikela=378776L=2
But this is very costy at 200EUR plus 20% tax. Do you guys have any idea
where to get vacuum party at more reasonable prices?
Jens
