Swagelok uses a compression-fit union meant to be used copper tubing or
brass fittings. To adapt to regular air or CO2 tubing, you buy a little
hose barb fitting from Swagelok for a buck or so. To adapt to 1/8 NPT,
they have another adapter, another couple bucks. I wish I'd shot pictures
back when I had all Nupro valves hooked to the regulator. All brass and
copper until the line going to the aquarium. Best quality stuff I've ever
used. When I expanded to four tanks, I sold it, replaced with ARO, which
was not really meant for the job, but did work. A year ago I bought
several used Fabco valves...they're nicer than the ARO valves, but the
fittings are plastic and the dial a little harder to adjust than the
Nupro, and the whole thing hooked up using hose barbs and silicone tubing
on both sides of the valve just has a flimsier, cheaper feel to it.
