CO2 regulator modifcation

[mkbillabo]

Hi all. I'm getting back into home brewing after a 4 year hiatus and I am looking to do my first keezer build. My question is about making a little jumper co2 line. Could I rig up a short jumper cable to connect to the FPT threads on a taprite regulator?

I would use something like this, correct?

My goal is to have a single regulator attached to the CO2 tank (I already have one), then in order to use the dual regulator I have, run a gas line with a barb to MPT connection that can connect to the dual taprite FPT threads, then proceed to be able to have 2 separate lines. I hope it makes sense, trying to get this posted before a meeting

Thanks all!

No!! That'd blow the hose right off the barbs! If you want to extend the high-pressure side you need the high pressure line to do it. The parts you're looking for are probably on this page:

Thanks! I am fairly unknowledgeable when it comes to the gas side. If i had a regulator attached to the tank set to ~30psi, would I still need a high pressure house if I rigged up the dual taprite regulator from that?

Maybe I just need to buy single regulators to simplify this and reduce danger. I'm just trying to save some $$

I must be missing something. You already have a dual regulator and you want to run two lines. So why not just use the regulator you already have as is? What purpose is served by the single regulator and jumper line?

Sorry... I may have misunderstood...(I think I missed the part about having a primary regulator)
You don't need to use a dual-primary..just get proper secondaries:

The duo tight ones are an order of magnitude cheaper. You can even get digital. Do you need different pressures? You can just use a tee if not.

Yes, this is what I would like, but without spending another $150. Any reason a small jumper CO2 line with a proper barbed/MPT thread wont work? It allows me to utilize a dual regulator I already have (FPT, meant to attach directly to CO2 tank). In my mind, I would keep the tank inside or outside the keeer (not sure yet, depends on freezer I get), have on regulator attached and run to a manifold (at ~30PSI). From the manifold I can rig a CO2 line to utilize my FPT dual regulator, and keep a line or two from the manifold open for future expansions/utilization.

I've seen some mixed opinions about their longevity. Do you have any experience with them?

Sorry, but I'm still not seeing why you can't just attach the dual regulator that you already have directly to the CO2 tank as it is intended. You can attach manifolds to each of the two existing barbs and run as many kegs as you want at each of two pressures, and still have the ability to expand further in the future either with or without secondary regulators. What are you gaining by trying to turn your dual primary regulator into a secondary regulator?

I doubt that the MPT/barb adapters you are looking at will seal properly on the input of a primary regulator, but you might be able to find some kind of extension/adapter that would.

Thanks! I think I just envisioned it a different way, but for sure this will work. I was being stubborn

Not yet but I’d like to get a few soon. I need to put a bulkhead in my kegerator and have been avoiding it

Hope I caught you in time: First; just so I'm clear, it sounds like you want to replace the CGA320 stem with a barb..
If this is right:

That's a Left Hand Thread. I can't find a LHT>barb on the taprite site, but I know they have a LHT>MFL available because it's available as a Taprite branded product here in Canada: https://www.ontariobeerkegs.com/taprite-1-4npt-1-4fl-reg-inlet.html
Hope I didn't misunderstand again.

If it really meant that much to you, I suppose you could try one of these

and a female NPT/barb.

Agreed, though get it with the LHT>RHT... my search-fu is in poor form today and I haven't been able to find one online.
@Bobby_M could probably source all the parts you need on request. brewhardware.com

The only reason not to just mount that 2-pressure unit directly to the tank is if you're adamant about not running two hoses into the keezer. The only way to get lower pressure CO2 into that regulator is with a 1/4" LHT to barb or 1/4" LHT to 1/4" MFL. I used to stock both until Taprite decided 2 pallets of regulators per year wasn't enough business and cut me off.

Thanks!

The inlet to the regulator is 100% left hand thread which is extremely rare.

Maybe leave the CGA320 stem on and try these?

Yes that's what I was getting at. No idea if it would actually work. And really don't think it's worth the trouble.
