I got in the 5mm ID x 7mm OD x 1mm from Granger but while the inside/outside seemed perfect for the glass/fitting the thickness needed to be  about x2~3 more or at least with mine fittings.
I image I can just stack them up.  Also the threads on my on the male/nipple are snarfed, so it is hard to tell if I am actually getting to where it needs to be.

But after all thing trying to figure things out, I broke the glass tube. Now to figure out what size glass I need to buy.  I welcome anyone that know this, I haven't a way to measure the glass circumference
