3 Gallon Keg System w/ new keg


SKU# 78513

Standard Shipping Rates Apply to this product

Same as our Draft Brewer® Single Keg System (K503), but with a new 3 gallon keg instead of a 5 gallon. The smaller size is easier to transport and takes up less fridge space, but won't hold an entire batch. Perfect for smaller kegerators and mini-fridges.

Best of all, it takes just a swish of sanitizer to prep your keg for the next batch. No more cleaning and capping dozens of bottles.

Includes everything except a CO2 tank to share and enjoy draft homebrew.

Didn't work at all
It took me more time to get this keg to function properly then to brew an all grain batch. I will go somewhere else for a better quality kegging system.

Nice start to kegging
This kit was nice, it had a leak when I first got it but I called northern brewer and they took care it fast and sent me a new keg for free. Really happy with northern brewer's customer service and definitely will be ordering from them again.

As far as kegging with this goes, it gets awkward when you brew a 5 gallon batch and have to split between bottles and this. I had to add about half the priming sugar after I kegged and bottled the rest. If you plan it out it's not that bad, but adds to the confusion of brew day for sure.

What is height of this 3 gal keg, both with and without disconnects attached?
A shopper on Jul 8, 2017
BEST ANSWER: I measure right at 17" tall with the couplers on as the hose arches up a bit coming out of the couplers and without them on right at 16 1/2" tall to the top of the handle. It is a great system, although you cannot remove the feeder tube inside the keg for cleaning.
Will CO2 cartridge fit keg?
A shopper on Apr 4, 2017
BEST ANSWER: Thanks for contacting Northern Brewer! I understand you want to use CO2 cartridges as opposed to a CO2 tank with this particular 3 gallon tank. I would not recommend using the cartridges for pressurizing the tank, because it would take several cartridges to even carbonate the beer in this tank. The CO2 cartridges (sku: 8083) are 74 grams and a pack of 2 are currently around twenty dollars. It would be much more cost effective to purchase a CO2 tank you can refill or exchange. Cheers!
What do I need to use this system with a CO2 tank and a Lat Straw bottle filler?
A shopper on May 15, 2017
BEST ANSWER: You need a way to split CO2 into 2 lines -- look for 2 way CO2 Manifold. The last staw has one CO2 line to the keg and one CO2 line to the straw valve for purging oxygen from bottles. I also found it helpful to purchase some extra nylon washers for your connectors.
Why does it say the poppets aren't removable? Mine removed for sanitizing without any issue. The included instructions did not indicate otherwise and I just noticed the description here.
K E on Jun 4, 2016
BEST ANSWER: Perhaps a change was made to the design, or the poppets used. The ones I had seen before on these new kegs were "pressed in" and did not fall out when the post was removed, like some styles would. The only danger would be damaging them if they were intended to be left in place, but if yours were easily removed and replaced, I would not worry about it. -Mike W, Northern Brewer
Steve C on Nov 1, 2015

Either will work just fine. You can carbonate serve 8-10 kegs with a 5 lb cylinder and twice as many with a 10 lb cylinder.

Are these 3 gallon kegs with hoes stackable in the fridge? It looks like the plastic ring at the bottom fits over the top of another keg.

M R on Sep 21, 2016
BEST ANSWER: These kegs are not stackable. They would not be stable if stacked.
Why are these poppets not removable? So the rubber o-ring can never be replaced?
V B on Sep 17, 2016
BEST ANSWER: The poppets are removable, although destructively. they can be replaced with the universal poppets.
Do you have a similar priced product for nitrogen?
B M on Sep 4, 2016
BEST ANSWER: We do not have a kit for this, but the 3 gallon keg can be used in addition to our Nitro Keg System (kx10)
Should I be concerned that the poppets are not replaceable? What does this mean for the longterm lifesaver of the keg?
J D on Aug 3, 2016
BEST ANSWER: Not a big deal, as they will last a very long time. If there ever was an issue, they could be pushed out and replaced with universal poppets. The ones in the kegs are pressed into place, and do not fall out when the post is removed from the keg, but they can be taken out of the post if they become non-functional. They'd be damaged if pushed out, so do not remove them if they are still working correctly. - Mike W, Northern Brewer
Which regulator typically comes with this kit?
C O on Jul 23, 2016

Thank you for contacting us. This system comes with our CO2PO single body regulator, http://www.northernbrewer.com/co2po-single-body-regulator

Is there a Nitro Version of this kit available? I'd like to have the option to use 100% nitro for Cold-Brew Coffee dispensing in addition to using for beer here and there.
M A on Nov 8, 2015

The closest thing to that kit as a nitro version would be the following:



Both of which are currently out of stock unfortunately.

On the other hand

we do offer the Jacked-Up Nitro kit:

What are the dimensions of the keg with the couplers attached? I need to figure out if thishis will fit on the top shelf of my fridge or if I should go for the 1.5 gallon keg system. I need the overall height as well as the approx diameter if possible.
S H on Nov 4, 2015
BEST ANSWER: This is 18.5" tall with the disconnects attached and had a 9" diameter
Is the keg included with this package the same as the standalone 3 gallon keg (SKU# 40374) offered by NB?
