MRbrew Updated 0-60PSI CGA-320 Keg CO2 Regulator, Thread Outlet with 1/4" & 5/16" Barb | Kegerator Regulator with Pressure Adjustment Knob, Beer Regulator with Safety Manual Pressure Relief Valve

This regulator replaced an old taprite that had started to leak. It seems to be made well and is not leaking(3 months after purchase). Leaving a review here to say that, while there are plastic washers included, my regulator came with a tank nipple that has a captive o-ring, like Taprite regulators have. This makes the plastic washers unnecessary. A little confusing for those who've never used regulators with a captive oring, but now i have extra washers for my other regulators.

Muy buena calidad y justo lo que necesito para pilotear el Co2 para carbonatar y servir mis cervezas.

I was preparing to host my daughter's wedding rehearsal dinner when I discovered that my CO2 regulator had a leak. No!!!! Gallons of homebrew at risk!!!! I had two days to come up with a replacement (and refill the tank) so I looked for options on Prime. I try to avoid devices that are obviously the same thing sold by multiple retailers because that's typically a sign you're getting a lower quality item. I ignored the voice in my head and bought this one anyway because it looked OK and I needed it fast. Big mistake. Come the day of the rehearsal I discovered that the pressure relief valve was defective. In the end I hastily hacked together parts from the new and old regulators and managed to get through the party without a CO2. I did not try to return the regulator because swapping out parts chewed up the soft chrome and I'd already resolved to order a brand name regulator. Avoid this and get yourself a brand name.

The unit itself feels cheap (though I do not have any others so maybe they all do) It works well. No leaks. Gauges seem to work well, and are consistent. I would buy this unit again. note: I am using this unit along with other appropriate attachments to carbonate water and other drinks in individual bottles. For this use, it certainly works well.

Using this for a soda carbonator running off a 5lb tank. I purchased a smaller regulator from Mr. Brew that does not have the tank pressure read out. That one leaked pretty bad, and I emptied a bottle when i forgot to close the bottle valve. After a year, that smaller regulator burst a seal and on the tank side and was useless. This valve holds pressure, and I forgot to close my bottle the other day, but did close the valve on the unit. Nothing leaked out. This regulator is much better quality, for the same price. Does a great job carbonating 2l of water at 45psi.

UPDATE Feb 10 2026 MRbrew has issued a full refund to me. We'll alow them the benefit of the doubt. The faulty part may have been an exception to their QC. Thank you, MRbrew for standing behind your product. Purchased MRbrew CGA-320 Keg RegulatorOctober 2025. January 2026 noticed that line pressure gauge became increasingly unreliable. I push homebrew and carbonate water, adjusting the pressure up and down daily. February 2026, pressure relief valve vented, with no way to reset it.i purchased a replacement at local shop. Higher price but better quality. The shut-off dial is inconvenient, requiring multiple turns rather than a 90 degree ballcock valve. And didn't enrich a billionaire.

I just went through a 10# CO2 tank and ran out to replace it. I put the regulator gently on the floor of my keezer when I left. I got home and reconnected the tank and there is air just POURING out of that nipple. The regulator is completely useless and such a waste of money. Edit: MRBrew reached out to me and sent me a new one. Updating my review to 4 stars due to customer service. Will update in a few months if needed to reflect the replacement product

I’m carbonating water in 1L seltzer bottles with this regulator. It seems to be a solid, well-built piece of equipment, easy to install, read, adjust and use. My only design quibble is the readability of the instructions. While reasonably translated and illustrated, they appear to have been designed for a larger page, then reduced and re-photocopied across multiple generations. That said, the company’s customer service seems accessible and responsive. I would recommend this device.
