Indeed.
In particular it seeps through almost all metals.

I was kinda wondering about that. Isn't H the escape artist of the

I think that's helium. They way they get it commercially is to start with
gas wells that have lots of it. I think some of them are 4%. Then they just
push it through quartz

How much hydrogen does a maser use? How big is the tank?
Does it leak through cracks or migrate through metal?

Well it's been an education!
First finding out how to identify if the Swagelok fitting is Metric by
sight and now how carefully the tubing has to be made to use compression
fittings!
I just went ahead and got the short section from McMaster Carr.
Want to make sure it's right if I'm at 400+ PSI with
Compression fittings work by crushing the surface
of the tubing, and the surface of the compression
insert together to make a gas tight seal.
Stainless is very tenacious stuff, and as a result,
when it is drawn through a die when sizing it as
tubing, it gets axial ridges formed by galling, and

Hi
The first thing that comes to mind with copper and stainless is that
they are not quite the same thing electrolytically (you make a battery).
That can be ok, or pretty bad depending on how wet your environment is.
There may be other issues ….

Bob,
That's the cheapest I have been able to find it.
I'll probably go that route with the expensive version as it's specified
for compression.
I know the original setup mixes copper and stainless but I have read that
is not recommended???

First one is a 2 mm wall at $75 a chunk. Second one is 1.5 mm at $33 a chunk.
It’s not
obvious why one is “compression fitting” and the other is “weld” rated. In any
case, I suspect
you need the 2X more expensive, done jus
Hi Corby
Is there a requirement for a specific alloy? I might have some odds and ends
lying around

This sound off topic but it's for a Hydrogen Maser modification!
The EFOS2 Maser is running low on Hydrogen and this time rather than
refill the compressed gas bottle I'd like to install a Hydrostik in its
place.
I have obtained all the fittings I need but have hit a snag!
I need a few short pieces
