A large ergonomic adjustment knob makes fine tuning your carbonation more than just standard protocol. Easy-to-read regulator gauge includes PSI ranges for major beer styles, and with a maximum range of 40 PSI, a higher resolution for dialing in exacting CO2 volumes. High-pressure gauge tells you when to refill your tank. Integrated check valve for safety. CO2PO® is here to serve your beer with nary a worry nor complaint.

  • Two regulator bodies for serving at two different carbonation levels at once
  • Machined brass body with stainless steel diaphragm
  • Rubberized gauges are easy-to-read.
  • Integrated beer style volume ranges on the dial face.
  • 40 Maximum PSI for improved resolution.
  • High-pressure gauge monitors tank pressure

I am on my third of these regulators. The first one was damaged out of the box, actual loose parts. The second worked for its first use. That night, it did something that caused it to blow off an entire tank of gas. I got a new tank and found that one of the emergency relief valves had failed and automatically opened under any pressure at all. I'm on my third, which seem to be working, but it's day one, so I'm not holding my breath. It *didn't* maintain constant pressure overnight, but that may have had to do with the beer so I can't blame the tool just yet.

A great upgrade.
I replaced an older single regulator with this unit and it functions so much more nicely.The knobs are much easy to turn and do quick fine adjustments, and I'm loving the ability to set 2 different output pressures. Now I can set serving pressure for one keg and force carb another at the same time!

The fittings for the CO2 lines to the kegs should be tapered to provide a leak free connection. The regulator I received did not even come with a plastic gasket.

Everything else on the regulator met my expectations.

Great Idea
The CO2PO Double Body Reg is awesome. It makes setting up my Last Straw effortless. I've retired my other refs in favor of the CO2PO Double Body unit.

Quality seems inconsistent at best
My first double body regulator had one gauge that was not accurate at all so NB replaced it for free. My second one was working perfectly until one of the regulators stopped regulating. No matter what I do, it keeps letting more CO2 into the keg. In the process of getting it worked out with NB right now.

I have had issues with other regulators not holding the specific pressure I wanted, slowly creeping up over time. This regulator stays at what I set. No issues

Decent but could be better
First time kegging with this and I set the pressure to 13 psi. Next day it was on 9 psi, so I turned it back up. Same issues 2 days later. Works well enough but I constantly have to monitor it.

Highly recommended product
This is a great regulator. The first one I received was defective (the second regulator did not limit pressure correctly) but NB sent me a new one without any problem. I use mine to either dispense from two kegs or forse carbonate one keg while dispensing from the other. I added a splitter on one line and now can run three kegs in my keeezer; two at one pressure and one at another pressure. Highly recommended dual regulator.

Don't buy this piece of junk.
I made the mistake of buying one of these a little over a year ago.

I wanted a dual body regulator so I could use one outlet for my kegerator and the other to purge and force carb my kegs.

The set pressure on this regulator creeps up on its own, annoying enough if it just over pressurizes my kegs, but I accidentally left the second regulator set to about 30 lbs. The pressure on that side crept up past where the relief valve opened and an entire tank of CO2 vented off. After my first negative review the manufacturer was nice enough to send me a replacement (thank you).

Unfortunately I had the same problem of pressure creep with the second regulator pressure and I lost a second tank of CO2, this time a newly refilled 20 lb tank. Enough CO2 to possibly cause a life hazard had it been in a small room (mine is in my garage).

I replaced these things with a new dual body American made Taprite that works beautifully. The old units are going to go into the trash, I wouldn't inflict these on another brewer.

Your mileage may vary. I see a lot of positive reviews, maybe I got two defective ones.

Easy to use and quick to assemble.
Worked perfectly in my keezer! I'll use it with my 4 connection gas distributor when I have more beer to share with friends and family.

My regulator is leaking out of one of the pressure relief valves. Is there a washer needed to fix?
A shopper on Jul 2, 2017
BEST ANSWER: Oh man! I wish I had a clear answer to this. I would check and make sure the valve pin is not twisted so that it stays open (like the relief valve on a corny keg), if not then try to see if the valve unthreads and see if anything in there looks busted.
I will ch do mine when I get home and see if I have any other tips for you.
Good luck! 🍻
how do you hook up a third keg with this?
Scott P on Sep 22, 2017
BEST ANSWER: You just use a T off of one of the single bodies to two separate gas fittings for your kegs. I use an 8 way manifold connected to a single body set to serving pressure. The manifold than splits to 8 kegs. My second body goes to another manifold to allow me to serve or carb at a different pressure.
Any future plans to just sell the regulator and the connector so that owners of the single body CO2PO can convert to dual without having to buy the entire $150 dual?
C O on Aug 28, 2016
BEST ANSWER: I would think twice. The dual gauges really add a lot of bulk and weight to your co2 setup. If I had it to do over again I would get signal gauge and utilize a manifold. Would save money and provide a more flexible setup.
Are these strictly for CO2 or can you use beer gas with it as well?
James J on Jun 2, 2016
BEST ANSWER: Beer gas regulators are completely different, and they are not interchangeable. Beer gas regulators are designed to withstand higher pressures and have a male connector instead of female, because beer gas canisters have the female end.
For what size hose is the barb/connector on the bottom of each regulator?
B E on Jun 17, 2016
BEST ANSWER: The threads are 1/4" MFL fitting, and with the right swivel nut, you could use either 1/4" or 3/16" tubing.
Can this system be flipped 180 and have all the ports and gauges work properly? In our Kegorator we would need the gauges and lines off the right hand side not left as pictured.
J U on Jun 10, 2016
BEST ANSWER: You would not be able to swap the high pressure gauge and tank connection stem but you could attach the regulator upside down.
Do the rubberized gauges replace the need for a gauge protector? I cannot tell from the picture if they are aesthetic or actually useful.
M F on May 26, 2016
BEST ANSWER: They won't protect against a significant impact, but they do afford some protection, enough for the small knocks around that can be relatively common in a kegerator that would damage most other regulators.
there is a table online called the Zahm Carbonation table. It shows you the ratio of temperature to pressure required to get a certain amount of co2 into your beer. but it does not specify how much time is required. what would be the timing if I wanted to carbonate my beer to 2.5 volume of co2 and for how many gallons will this be true for?

Are there check valves in the outlets?
