Not bad
This regulator came with my keg system. I was a little skeptical about it because of the reviews but after getting it an messing with it for about a week i got it dialed in nicely. The adjustment knob is a little finicky but once you get the hang of it I have had no issues with it holding PSI. Gave it 3 stars because its not very user friendly especially if this is your first keg system. But overall it works

worked great for about a year...
Bought this in August 2016 as part of the 3 gallon keg system. Worked great for about a year but now seeing the same issues as others are reporting. Biggest issue is the regulator will not hold a constant pressure. I will set the pressure at a specific point and it will gradually increase over short period of time. No longer set it and forget it. I have to constantly monitor, adjust and purge to keep my beers from over-carbonating.

Ok
This regulator seems okay at first and does the job when you first start using it; although it does act very oddly when trying to set a specific psi. After my first 5 gallon keg force carb and serve it has completely stopped functioning correctly. It will jump psi all over the place and one time I opened up my fridge and beer was just foaming out of my serving line. It seemed to jump up over 20 psi overnight.

Response from Northern Brewer
Most of the time this is caused by a small piece of debris from manufacturing. Best way to fix this is to start with just the regulator hooked up to the co2 tank, no hoses or kegs. With the co2 tank turned off, open the valve on the regulator and turn the pressure of the regulator up. Now turn the co2 tank on and off a few time quickly to send blasts of co2 through the regulator. The quick burst of high pressure will often clear out any bulking the diaphragm from holding the correct pressure. Give that a try and see if it works. If that does not do the trick then it most likely a faulty regulator and we can get you a replacement.

I am liking this!
This was a replacement for an older model that started failing after 2 years of use (suddenly started increasing pressure until venting). Anyway NB promptly replaced (was not expecting that so many thanks for fab customer service!).. this new regulator has been working very well (6 months in)... fine adjustment, sturdy, for me it has been holding pressure fine. I am only running a single manifold so no carbing while serving at this point. Anyway, contrary to some of the other reviews it is working well thus far.

Nothing but problems.
Bought this as a 2nd regulator to take to parties, etc. I have had my previous regulator for over 5 years and have not had a problem. When I have the washer between the tank and the keg it leeks. When I take the washer out it still leeks. I set the pressure at 10 psi one night in order to start carbonating. I woke up the next morning, the pressure was at 50 psi, the keg was empty and the bottom of my fridge was full of my Vienna Lager. The pressure popped the tap hose off. If I could select less than one star I would. I notice that NB only sells this brand of regulator now so I will need to look elsewhere for another.

Great product
Bought my regulator last year and the first initial one I received did not work. I made Northern Brewer aware and they sent me out a brand new one immediately. My new one works great and I haven't had any issues with it since.

Pressure drops a lot
First time using this regulator, I decided to burst carbonate my amber ale , so I hooked everything up and set at 30 psi . The lower gauge read at just over 800 psi on a brand new gas cylinder. But for some reason top gauge at 30 psi kept dropping to 20psi in a matter of an hour ! Next thing i knew 2 hours later my bottom gauge dropped from 800 psi to 600psi .Im losing a lot of gas and I checked for leaks and found none.It my first time kegging a home brew , so im thinking "what am i doing wrong ". Well , from looking at these other reviews , looks like other people are have the same problem.

Regulator increases pressure over time
Concur with the other reviews about inaccuracy and the regulator not holding a constant pressure. Doesn't matter what level you set it to, it will not hold the pressure, and continually increases pressure. I once set it to 20 psi and came back 12 hours later and was pegged at 40 psi, Beer became over carbonated - wasted gas, etc. I would not recommend.

Great unit
If this is all you need it's a great one to have. This is a back up for me, was very pleased with this regulator.

Is it possible to later screw two CO2PO's together into a double regulator?
C S on Jul 11, 2016
BEST ANSWER: While I have not personally done this I believe it is very easy to manifold two units together and have separate setting for the amount of regulated pressure you want. Both units should be under tank pressure
What is the plastic o-ring for that comes attached?
A shopper on Dec 31, 2016
BEST ANSWER: It's not plastic it's nylon. Very very important, it's a CO2 washer that will seal the regulator to your gas tank and prevent the tank from draining in ~2 days. Make sure it's put on in the right direction. If your tank drains quickly is usually the washer and regulator not tightened enough.
Can this be attached to a paintball tank?
A shopper on Dec 25, 2016
BEST ANSWER: I'm not familiar enough with paintball tanks to be 100% confident. BUT the small paintball tank that I have for taking my beer on the road needed an adaptor to get it hooked up into my CO2 regulator.

This regulator fits a standard CO2 tank just fine, your paintball tank would need to adhere to those same standards in order to work with this regulator.
What is the thread size for hose connection (out) - is it 1/8-27 or 1/4-18?
A shopper on Feb 1, 2018
BEST ANSWER: On mine it is a standard 1/4 MFL connection used for a swivel nut. If you are looking to thread this to a standard piece of pipe you would most likely need a 1/4 MFL to 1/4(or whatever size you want) MPT adapter.
Can I put this regulator and a 2.5 pound tank inside my fridge? I use 3 gal kegs and open the door to draw a beer. I have been filling them with gas then removing the co2 line. (wife not in favor of hole drilled in fridge).
A shopper on Jul 28, 2017
BEST ANSWER: I have the same setup as you are describing. I keep my 3 gal Keg laying on it's side on the bottom shelf of the fridge. I then put the CO2 bottle upright in my fridge door on the lowest shelf. When I get to half full on your keg I have to pull out of the fridge and stand upright to not draw air with my beer. I have read you want to keep the CO2 bottle upright or risk drawing liquid CO2 into your beer. Not sure on this as I never tried leaving a CO2 bottle connected on its side.

You will notice the pressure in your CO2 will decrease with temperature. So you will need to increase the pressure knob to maintain the pressure you want as the CO2 cools down. Otherwise you may see beer creep into your CO2 line.
The ergonomic knob on my co2po is stuck. I've just tried to use it today. Any ideas how to release the lock to enable the knob to twist?
PATRICK M on Mar 10, 2018
BEST ANSWER: I have had this happen to me, there seems to be manufacturing flaw. If you store your tank inside your cooler the system seem to freeze up, I don't how or why but it does. I moved my tank to the outside of my cooler and haven't had any trouble with it since.
New regulator and my low pressure gauge needle does not go below 30 psi, even when disconnected. Is it defective?
A shopper on Feb 12, 2017
BEST ANSWER: Yes, I had the same thing happen to me. Just give customer service a call and explain. They sent me a brand new one free of charge
How do I get parts for this?
Tony B on Mar 19, 2018
BEST ANSWER: There aren't replacement parts available for this regulator. Cheers!
How many 5 gallon kegs will this support? Do you have to have one for each?
A shopper on Jan 14, 2017
BEST ANSWER: One keg can be hooked up directly but you can get a co2 distributor to connect multiple kegs.

The ergonomic knob on my co2po is stuck. Any ideas who to fix?
A shopper on Mar 10, 2018
I have this regulator and damaged my high pressure gauge. Do you know if the high pressure gauge is left or right hand treaded so I can order a new one?
