The slim 7
« on: February 06, 2012, 11:30:54 AM »
Last week I scored 4 kegs, a CO2 bottle and regulator off Craig's list, $100.   :-*

The bottle turned out to be a slim 7 lb bottle.
I cleaned the keg fridge out really well this weekend, and now I can get 5 kegs in there with the bottle.
Perfect height as well.

Are these slim 7 pounders very common?  They sure work well for space constraints.



Cheers!

That looks like a repainted O2 tank. Anyway I've never heard of a "slim 7" but it looks like it'd be useful for those with limited space.

I've never seen that either, maybe it's more common in your area.  I'll look around next time I get gas, I've got a couple of empty bottles so I'm due.

Interesting.  Is an O2 tank painted a particular way? 
I guess they would they would be interchangeable? Gas is gas right? 

Works great for the space. 
Now I have my "squat 5" for around the house use/keg cleaning. ;) 
Yeh, I made "slim 7" up. :-[

It looks like a medical O2 tank which are green on the top. Yeah I've always wondered what the difference was except that differences are probably just to keep gases from being mixed up and being in the wrong tank.

Medical tanks have a different valve on the tank, and the flow regulator is different.  Search for medical O2 tanks.

If you search on O2 tanks you will find industrial ones that look like what was shown.  Been a long time since we had welding safety in the lab.  I was not a welder, but had to take it.

It should have different threads so you can't accidentally hook up the wrong thing though, right?

The valve on an O2 tank has left hand threads for the regulator, if I remember correctly, but who knows if you can swap over a different valve and screw it into the tank.

If I remember correctly (big if, somedays) the valves are interchangable.  The color the tank is painted is based on content so you don't hook up the wrong tank and so emergency personel can tell quickly what theyare dealing with.  If the bottle can be hydro tested and stamped correctly for the gas going into it, you're good.

That's the first time I've seen a slim profile CO2 bottle. I am going to contact my local gas house and ask if they can get them. The slim profile would allow for more room in my kegerator.

O2 has left hand as Jeff has said.  The tank valve in my 10 LB CO2 tank would not fit into the opening on my medical O2 tank, as the diameter of the valve to tank threaded fitting is of larger diameter.

I found out today that you guys are correct, it is an old medical O2 bottle that has been refitted, tested and stamped for Co2.

The guys at the welding shop didn't know what to call it, but they filled it and wrote it down as a custom-er owned 10 pounder. :o

Cheers.

I would be afraid of anything out of the ordinary. Can you always get it filled and will they charge you more? However it sounds like you got a good deal on it, so why not. 


Why don't you mount it outside your kegerator, then you won't have a space issue.
