DetailsOur newest CO2PO® Regulator is built to serve. Fluent in all Beer Styles (and sub-styles), CO2PO® is here to recommend precise carbonation for your home brew. Built from solid brass, the regulator body features a stainless steel diaphragm — instead of rubber — for improved stability. 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, CO2PO® allows for a higher resolution for dialing in exacting CO2 volumes. Its high-pressure gauge tells you when to refill your tank, and an integrated check valve ensures your safety. CO2PO® is here to serve your beer with nary a worry nor complaint.
The double body regulator has all the features of the CO2PO® Regulator but with a second regulator body. Two regulators allow for serving two different beer styles at their ideal carbonation level. Or force carbonating one keg at a high pressure while pouring another beer at serving pressure. Pairs well with the Last Straw™ Bottle Filler.

2.4 / 5.08 Reviewsco2 regulatorI like the regulator but I thought the gas connection was barbed and not threaded so I had to buy new barbed connections so I could use it.December 11, 2018Purchased
11 months agoDidn't even last a yearStarted going through CO2 quicker and quicker, last bottle I hooked up, blow off valve couldn't handle any pressure and started draining the tank instantly. Its really poor quality compared to other brands out there.August 9, 2018Works great!!Works good!! Already had to replace one of the ball valves because it was leaking. Other than that works great.July 13, 2018Purchased
1 year agoI would definitely NOT recommend this product. both of my gas-out posts snapped off on the first use, the metal is extremely poor quality (looked like particle board on the inside) The worst purchase I've ever made. Zero stars.January 22, 2018Purchased
over 2 years agoGood product if you don't mind drift.I really like the dual control for different pressures and it appears to be well built. You need some patience though as the pressure drifts. I have a single gauge I can set and forget but I need to adjust this once or twice a day for two or three days before it settles in.April 7, 2017Purchased
over 2 years agoHuge Disapointment... Now it is useless junkI received this for Christmas and was excited about it. The first time I used it I went through a 10 LB tank rather quickly, after securing a new one I re-checked all of my equipment and went to check the fittings on the regulator and as soon as I put a wrench on one of the blow out valves is sheared off. It is now useless unless I swap all of the gauges out for a new bodyApril 1, 2017Works great.I have had no problems with leaks mentioned in an earlier review and have been able to dial in my keg lines without issue. This was part of the Keg n Brew kit from Midwest that was on sale for $250 and included the last straw filler along with a new ball lock corny keg and all of the tubing and locks needed (a really good deal). I like how the gauges are somewhat protected by the rubber covers. Note that if you connect this to a 5 lb CO2 tank, you must support the tank or it will fall over as the regulator is substantial and can topple your tank.January 31, 2017Worked Fine, but leaked all my CO2 from the tankI recently purchased this item as part of a kit including the Last Straw Filler. I hooked the regulator up to my 5 lb C02 tank as instructed (using no teflon tape, but with the enclosed plastic white washer). I force carbonated a small 3 gallon keg of beer within about 2 days, and it poured fine (I poured about 2 pints).
However, a few days later I returned to the tap and it was not pouring at all; when I checked I found the CO2 tank completely empty. Obviously this should not happen from carbonating only one 3 gallon keg of beer, so I am assuming there is a leak someplace in one of the regulator connections. The product came with gas lines pre-clamped, and I did notice that the lines were far from flush with the connectors, but the clamps seem tight and I noticed no gas escaping.
Possibly teflon tape should be used for the connection to the tank, even though the instructions specifically stated not to do this? I didn’t notice any obvious gas escaping at any point from the regulator, so I’m not sure where the leak is coming from.
The beer is still carbonated and I know the issue isn’t in my 3 gallon keg, as I was able to hook up my old regulator/tank and get pressure instantly, and a good pour. The beer is carbonated well
This is very disappointing since I spent $40 to fill a tank of CO2 that poured only a couple beers; Now I will have to go swap out my tank for a new one. I am hoping to find the issue before wasting another $40 on another tank that will just drain the same way.
If this issue is addressed I would happily rate this product 5 stars since it seemed to be functioning very well and I liked the ability to dial in the carbonation of my beer (the beer is carbonated exactly right!). I didn't have a chance to try it yet with the Last Straw Filler before I lost all my CO2 (the main reason I purchased this regulator). Maybe Midwest can advise on how to address this issue?December 18, 2016
- Customer Q&A
Browse 6 questions Browse 6 questions and 6 answersI can’t get the second dial below 30 PSI, but the first one works completely fine. This is the first use, any suggestions?I can control the dial on my first keg, but one the second dial away from the tank, I can’t get the PSI below 30. This is the first time I’m using it. Any suggestions?BEST ANSWER: Make sure that you are bleeding the line as you lower the pressure. Otherwise the dial won't drop.What size are the gas nozzles? What size hose connects to them?As far as I can tell, the gauge that measures how much CO2 is in the tank does not work. Any suggestions?BEST ANSWER: How big of a Co2 tank do you have? I have a small tank (2.5 lb) that the gauge basically shows always empty on every regulator I have tried. But on my 10 lb tank, it does show like "barely not empty" and does function, but doesn't appear like it is totally full. I've found this to be the case on all of my regulators, though, not just this one. Not sure if it's a pressure thing or what. Might make sense for these manufacturers to offer a "lower pressure" gauge of sorts for smaller tanks, I guess, but I've mostly just relied on decreasing and eventual lack of pressure to let me know when my tank is drained.Does this come with a gasket to hook up the co2 tank?BEST ANSWER: Yes it does.This unit (when attached to a 5 lb tank) seems top heavy. What is the best way to keep this from tipping over?BEST ANSWER: Bracing the regulator against a surface tends to help, you can also use a small cut board to prop up the regulator. Or use a pipe strap to secure the tank to a wall.
