CO2PO Double Body Regulator....
I sent it back to NB the day after I received it... The day I got it I hooked it up to my CO2 cylinder and tried to adjust the pressure....it was extremely hard to get the right pressure because it moved 2 to 3 pounds at a time....even if you turned the dial as little as possible ...WAY to touchy to adjust....I have a 20 year old TapRight regulator with the machine screw and nut in the middle of the dial...and it works 100% better then the CO2PO...I bought the CO2PO BECAUSE it was SUPPOSE to be easy to dial in the pressure and I could hook up two kegs at different ..This one wasn't ...I'll stay old school ans stick with what I've got...

1 of the 2 regulators work great.
(Bought at LHBS) I like the displays and the sea urchins protecting the gauges. However, one of the regulators is a PITA to dial in. I'll sit there for a solid 20 minutes trying to get my desired serving pressure and when it's been at the right pressure for 10 minutes I'll walk away. When I check on it the next day it's 10-20 pounds too high. I set it to 8 pounds and it held for 10 minutes, the next day it was 23 pounds. When I purge the pressure and try to adjust it takes forever for the co2 to flow through the lines. I'm constantly having trouble over carbing my beers now. I decided to use the one that works as the serving line and the other as a utility/force carbing line. This is very unfortunate for such a promising regulator. My Tap-Rite regulator still works great. (The regulator that gives me issues is the furthest from the tank)

Very Disappointed
After 2 days, the pressure relief valves blew out thus draining the fresh tank of CO2. Northern Brewer replaced the item and sure as shooting, the second regulator had the same issue and losing another tank of CO2. Going back to Micromatic....

Good quality, easy read fails. Very balky, the dual gauges really add a tip risk.
August 25, 2016
One regulator is extremely sensitive and takes a lot of careful tweaking to get to the desired pressure. The other regulator is apparently defective, I have to twist the knob all the way in to get any pressure, then it goes from nothing to full throttle. This is the most expensive unit I have seen and thus had high expectations. I used a Taprite T752HP in the past and I think that I will switch back to that model.

Sorry about the trouble with the regulator! We've had pretty good luck with them so far, we're sorry that this one gave you so much difficulty! - Mike W, Northern Brewer

Looks good But
It looks good it feels heavy but the regulator won't be very accurate when you turn the knob you have to turn it like 4 times for the needle to move.
I also had an issue with pressure release valve on one of the valves, there is a white gasket inside of it that fell off, causing some CO2 loss, called customer service, (very good customer service by the way) but they don't offer spare parts for that, so had to figure something out with Teflon my self.

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.

Not any good,
One regulator works ok so far but is still sensitive to set. The other regulator creeps up and pegs gauge in two days. I have valved off keg and backed adjustment all the way counterclockwise and it still maxed gauge in two days. Spend the money for quality regulators.

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.

This regulator rocks!
I would absolutely recommend this regulator, especially if you have multiple kegs or the "Last Straw" bottle filler. I have both and they system works great!

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?
