Tony!
Thank you for the link!!
I have reviewed the bulk of the catalog and glean that while a few of the offered fittings are for 1/8" OD Tubing, most start at 1/4" OD Tubing.
The MIP x VCR Tubing adapter cannot be used with the retainer gaskets, the smallest size for that application appears to be 1/4".
It also appears that a coupling would need to be installed directly at the MIP x VCR adapter, for which there is no room in the small space of the box cover. The current tubing has a 'U'-turn bend in it to miss the cover.
Looking at perhaps a 90° MIP x VCR Tubing fitting, may or may not fit into the space needed, I'm doubtful that it will, especially at the main air block, there simply is no room for an elbow, only a straight adapter will work.
I am awaiting an answer from Parker Hannifin on their edition of a fitting that may work.
This is the current tubing configuration....

The OP’s parts are not the Swagelok VCR fitting. I welded hundreds of VCR fitting to tubing with an orbital welders when I worked at Swagelok. The VCR is a very unique fitting that entails using two VCR’s facing each other but with a metal gasket between the faces. It is also a very costly fitting.

I used to use 1/8” fittings on my scuba flow bench. I am assuming your booster goes to at least 4,500 to maybe 5,000 psi.
Go McMaster Carr and search 1/8” Yor-Lok fittings. You will find 1/8 tube to 1/8” NPT fittings. They are rated for 6,000psi for stainless and 6,800 for steel. Considering they see moisture, I would select Stainless Steel. They ain’t cheap but I don’t think you’ll need many.
PM me if you need assistance. I used many of them on my scuba flow bench when I built it.

Thank you for the input!I initially had the Yor-Lok fittings in my Shoebox spreadsheet as I had found them as you stated, on the McMaster-Carr site. (Much of the parts for the Boxes are from McMaster-Carr, so it makes sense from a purchasing point, I suppose.)
However, they are not the same fittings as the OP, which seem to be a swaged fitting, likely using a hydraulic swaging tool (?).
There were a few iterations of fittings on the Shoeboxes as they went through the 'Betas' to the F-8/10 models. The F-8 is the one that I have and include the OP fittings.
Yes, the Box will easily go to 4,500PSI, that the auto-shut-off rate too.
I'll head back to McMaster-Carr and check the Yor-Loks out more closely.
Sounds like your experience is hugely valuable in locating this sort of fitting (that's why I'm asking on AGN, HUGE knowledge base). While I have used many fittings in my career, (Swagelok in particular) I never ran across the swaged 'Barrel-Style' fittings per the OP.
