c02 thread size

ghohn

There are a few of the guys here in Daejeon looking to build kegerators but we've kind of hit an impasse with the sad passing of Joongnang keg guy. I've been thinking of work arounds and came up with this and am only caught up on one detail: C02 tank thread discprency.

This summer, I built my hillbilly kegerator using a picnic tap, beer keg, c02 pinvalve regulator and 1, 20 ounce paintball c02 tank. It worked great.

As I get free c02 (#20 lb) from a forum member here (thanks forum member!) I could act as a fill station for other Daejeonites. I used to work at a paintball field so I'm quite familiar with filling tanks. Used C02 tanks are DIRT cheap, and extremely light when empty, in the US and we have a guy heading back that could act as a mule.

Of course, guys would probably want to naturally carb their beer because the constant trips to my house might get tiresome, but for setting lids and pushing beer, I'd think you'd get 2-3 kegs per right?

I'm going to check with my C02 hookup to make sure it's cool with him before I proceed. My only question is will a C02 fill station adapter fit a C02 #20 lb cylinder that comes from Hite? I remember Wamille had to get something rethreaded but can't remember exactly what he was working on at the time. ~ Thanks.

US and Korean CO2 thread pattern is different, both Bill and I had the Jungang guy swap ours out, he charged us W5,000 for them. I'm not sure what the Korean spec is, but swapping them out is an option if you can find a source. I do have an adapter that I could sell for W5,000 Korean spec keg to US spec adapter if I can get the damn thing off! My wrench is too small for it, I got this when I helped one of the on base guys source a CO2 cylinder and he didn't want to swap anything out. So if you have any ideas on how to get it off, it's yours!

Sweet! I have a crescent that goes up to 25mm that's plenty for my C02 reg. What size do you need?

Out of curiosity, where did you pick up that adapter? Do you have a link so I can get a better visual?

Kunkemonster

My wrench only goes up to 200 mm. I got the adapter from the Jungang guy as well; I just checked and it has no markings on it, if you could find the thread pattern of Korean CO2, I'm sure you could get them from the states.

ghohn

Do you think a 25cm would fit it? Do you know what the different thread patterns are called. I have no idea what to Google. At any rate, it's good to know it's an option. I'll get back soon on this. Thanks.

Kunkemonster

Haha I just realized 200mm and 25cm probably isn't how big of items the wrench can handle, but probably refers the overall length of the wrench seeing as 200mm is closer to 8 inches. Anyway It looks to be around 1 and 3/8th inch.

I was thinking, "That's a big wrench!" 30cm rulers are the standard for Canadian (and other non-American, non-Burmese?) schoolchildren. You know, the ruler the nun beats you with? That's a 30cm ruler. Unless it's a meterstick, in which case your nun is a real hardass.

Not that any of my teachers were ever nuns, but...

Kunkemonster

My coworker let me borrow one of his wrenches, the adapter will be off the tank tonight. I'm assuming you still want it?

ghohn

Yes that would be great! Just PM or FB and let me know where to send you the money. Thanks!

Well I'm fairly new here, and trying to get my stuff setup. I was able to acquire a CO2 tank from friend, but my regulator won't fit onto the cylinder valve assembly. I was reading about the difference in thread patterns, does anyone have information on if I can take my regulator in and get the parts to fit the gas cylinder. Its a full size cylinder, versus the little 5lb one I had from the US. Looking for something in the Itaewon or general vicinity if possible.

Kunkemonster

So you have a US/Korean regulator/CO2 tank?

budice02

I have a Draught Technologies regulator(US) and was able to acquire a full size CO2 cylinder(Korean-Hite). Trying to figure out how to put slot A into Tab B without soul crushing brute strength.......hopefully the equipment will still be usable, but not for much longer. :x

Went on a wild goose chase today to see about finding a CO2 distributer my realtor had looked up for me(North of Dongguk University Sub Stop on Line 3). Turns out the number and address were both wrong so egg in my face. I guess that is why they are in the realty business and not the beer business.

Kunkemonster

I bought a US regulator too, I had the nut of it swapped out with a Korean spec nut and it works great. Unfortunately the shop is no longer around, it is possible if you can find a place with spare parts. I'm not sure if the new CO2 refill place has spare parts, I haven't been there yet.

budice02

Found a place that was able to change out nut on the US regulator. They said they can provide CO2 tank and provide refills, with a two day turn around. Just on the north side of Namsan Mtn about a 15min walk from the Dongguk University Sub Stop on Line 3....I'll post directions if anyone needs them.

Awesome. Do you know if they sell regulators as well? Do you have a phone number?

budice02

I think they might sell some regulators, or at least can help you acquire one. The sheet with the number is at work, I'll post it on Monday when I go back in. If you need it sooner I can stop by the office tomorrow. Sorry for the late post, hadn't been on in awhile.

just got a regulator and ball lock combo from the states and ya different sizes. I took it to the beer distributor in suwon and he gave me a hite regulator for free. I did pay 90,000 won for the co2 tank and am not sure if that is for free refills or not. i will find out in a few weeks.
Any one know where you can refill near suwon? Also do they refill hite co2 tanks?

I've got the same 90,000w deposit Hite tank you have. Good information about the regulator though. We are still out of luck down here. I think the easiest course of action is to take that adapter I got from Bryan to a machine shop and get a few of them made so we can pick up US regulators. I gotta believe it will be pretty cheap.

I have never refilled, read about it though. It looks like the end of the refill station that connects to the tank is the same as the one that goes on the regulator. I am only guessing here but I would expect the beer distributor to have the parts to repair regulators, thus the fitting to connect to the Korean tank. I was the same as 1234 in that he gave me a used regulator for free. I got the idea the guy at the distributor liked beer so you can never tell what you can get for a few bottles of homebrew. ;)

If your goal is to refill US tanks then you will need one end to fit the Korean tank and the other to fit the US tank. You could do that with a US refill kit and the one adapter. If you want to refill the Korean tanks, I understood the distributor can get them refilled but it will take a few days because he doesn't' stock them. Seems easy to me. I also understand the the refill would be a "Service" at no cost. Hopefully I will have something bottled that is drinkable and I will give him a few when ever I want to refill. Sure beats traveling to Seoul (carrying the empty tank), pay for the C02, and travel back (carrying a full tank). Cost more the 30,000 won. The bad part was that on my first keg I found I had a leak. :(

Another thing about refilling. The bottles they refill from have a dip tube. The ones from the distributor don't. Did you plan on inverting the 20lb tank when refilling? With purging I would guess maybe 3 5lb tanks per 20lb tank. You could maybe improve that by first freezing the tank to be filled. Salted bucket of ice might work also to chill the bottle.

I was planning on filling paintball co2 tanks with that adapter not other co2 tanks.

dadd_55

Still you will need to get liquid CO2 and not just gas. All the videos I have seen make note of the dip tube in the large bottle. I don't think you will be able to get any volume otherwise. I would guess that if you have the source tank upside down you will get the liquid needed but not sure how safe that will be. Here is a link to a PDF I found that talks about it and the safety involved. Hope that helps.

Here is a link to a paintball forum discussing this by some smarter then me. #27 talks about the fill station tanks and inverting a regular tank.

Awesome! I had no idea that was the case. You definitely saved me some frustration!

dadd_55

It does appear that you could do it by inverting the tank. You would want to make sure you have a good way of supporting the tank so as not to have it drop and possibly break the valve. You made a "Rocket Stove" but I don't think your goal is make a "Rocket", at least not in the apartment. The adapter should be easy to build if you can just source the tank fitting from a regulator. Not really sure about the paintball tank fitting but guess you must have had one when you built yours this summer.

Good luck, be safe. Don't want to hear how some 미국 blew up a building making beer. ;)

I'm a big fan of this regulator. here . It works well and is really compact.

As far as filling goes, my parents used to own a paintball business. I've logged countless hours filling tanks for them but never took the time to inspect the adapter.

I think what might be the best route for the guys looking to setup a kegerator is to have a handful of those Korean -> USA thread adapters made by a local machine shop and have regulators shipped from the US. Shitty, yes, but beer must be dispensed.

You forgot Liberia.

dadd_55

I am guessing that if you already have a regulator you could use something like this:

I have seen the high pressure flexible lines in the stores here. As for filling all you would need is one of these, a flexible high pressure, a 3 port manifold, 2 shutoffs, and a connector to the main tank. Seems doable. I understand the difference is not in the adapter but in the tank itself.
