SS-4C-1/3 ideally, but SS-4C-1 should work fine as well. And you can probably get one or more of them for $20-ish shipped. But you'll need tubing inserts designed for standard 1/4" OD by 1/8" ID tubing. Swagelok # is SS-405-2.

Will the JBJ bubble counter fit with SS-4C-1?

Yes, but it will be very tall and you'll need two tube adapters for mounting it. You'd be better off with a glass bubble counter.

SS-2C2=1/3:
SS = Stainless Steel 316.
2C = 1/8" check valve.
2 = male NPT threads 4 = female.
1/3 = 1/3 psi cracking pressure.

SS-4C-1/3:
SS = stainless steel 316
4C = 1/4" check valve
no suffix after the 4C = compression fittings.
1/3 = 1/3 psi cracking pressure

So the SS-4C-1/3 is designed to work with either metal or soft tubing. If you were determined to run it mounted, you could do two SS-4-TA-1-2, which will add maybe 1 1/2 inches to the height of the valve.

I'd still recommend running it inline, and a bubble counter (not a JBJ-style, I strongly feel that they're complete garbage) also inline. Though I suppose you could use one adapter at the top of the check valve and screw a JBJ onto it, running both of them inline.

Default CO2 Regulator Assembly

Is there any CO2 regulator assembly available for sale. I'm looking for one for my new 70gal freshwater natural aquarium.
Thansk.

Thanks for the info. Very useful for me.

Is it just the photo or is that port not threaded? An expanded pic should help more as well.

The relief valve would go there.
