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 of 10mm OD 1 or 2mm wall stainless tubing to
go into the Metric Swagelok fitting.
However all I can find on the net would cost me over $100.00!
Does anybody have a few short lengths (two 3" and two 4" if cut ready to
insert in the fitting) or one 18" piece that I could buy at a reasonable
price???

Thanks,

Corby

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 just for compression fitting versionl. If anybody
is looking in their junk box, time to take your calipers out and check if that wall thickness
is 2.0 mm or 1.5 mm (I guess …).

Hi Corby

Is there a requirement for a specific alloy? I might have some odds and ends lying around
