So, my friend just moved into a house she is renting for a year and found 10 large tanks of Nitrous Oxide that she believes to be full. I attached the pictures she sent me. I was wondering that equipment is necessary to use these? I assume you need a regulator, but I have no idea where to even start to find out what kind I would need, or what other equipment is necessary. Does anyone here and any experience with something like this?

Sorry, can't help you there, but check out ebay, you'll likely find all you need. Also a word of caution, make sure the nitrous is not intended for use in automobiles. Additives are sometimes added to nitrous tanks to prevent abuse.

Thanks. Since it says InterMed on it, I assume the tanks were originally for medical use, although anything could be in them now I guess. Does anyone know if the parts for medical nitrous tanks are compatible with parts for CO2 tanks? My roommate has a CO2 tank with a regulator that we use for making soda and for powering a keg. However, I wouldn't be surprised if all the parts were different. The nitrous tanks aren't in my possession, so I can't just check.
 
the tanks have the name of the fitting - CGA 326 - writeen on them. its a special fitting for nitrous, which is an oxidising gas.

find a cga 326 e.g. baloon filler and you're a laughing man.

Thanks for the info. I didn't know that cga326 was nitrous, so that was quite helpful. When searching for cga326 valves, I kept coming across stuff like this:

I understand how stuff like this works. However, it appears that the bottles have something like this on them already, except instead of a knob to control the valve, they have some kind of nipple. Does anyone know how the current equipment works? Like, is it already a functioning valve, or do I need something else? I really can't remove the old equipment to replace it because I don't want to lose all the gas. Also, when you mentioned looking for a cga326 balloon filler, did you have a specific product in mind?

There's a bit of complexity when choosing a regulator, unless you buy a regulator specifically designed for nitrous and proper PSI, there are a lot of considerations. You should educate yourself cause compressed gases are no joke.

Now that I think about it, I might not need a regulator if I can just have a working valve. The goal is just to fill balloons, not set up a mask or anything. And I have some experience with compressed gasses. I've used an industrial air compressor to paint a car before, and I have experience with a CO2 tank that I use to power my keg. The problem is that a normal person can't just walk in the store and ask for help setting up a nitrous tank. That's why I'm asking you guys.

Also, I know I said it at the top, but these tanks really do belong to a friend, not me, so I can't mess around with them myself right now. It's just that my friend knew I had experience with a CO2 tank, so she asked me for help.

Thanks

that little screwy nipple thing looks like one of those valves with the turning part taken off to me
 
So after doing some more research, it appears that it would be quite dangerous to use it without a regulator, as the sudden release of pressure could send the tank flying through a wall. However, regulators seem pretty easy to come by. As far as opening it, MrPorter's idea seems quite plausible. Does anyone else agree?
 
usually tanks come with one valve welded on the top (in the 3rd picture its the hexagon-type thing on the very top. someone has removed the handle) and you affix your regulator that has pressure gauges and a fine control on the nipple on the tank.

don't remove any of the existing stuff from the tanks unless you want to get injured or killed. don't open the top valve w/o a regulator on the nipple either.

please excercise safety around gas regulators, make sure they are installed correctly and of the right kind. don't ever jury-rig compressed gas lines.
 
The gas you have has something other than Nitrous Oxide in it, Nitrous oxide is a Green tank. You need a low-pressure regulator to tap the tank, but I think you will find it has had sulpher gas added to make it un-inhalable.

Well, a portion of the tank has the fitting name for nitrous and there's clearly a sticker on the tank that says "nitrous oxide" in the first picture, so it seems to be NO2 in the tank.
 
i would bet on that being medical or scientific grade nitrous. but yeah anyways you can most likely buy the parts online, or find an industrial or medical supply warehouse. im sure if you give them the serial number of the top on the tank they will be able to point you in the direction of a regulator that will fit.
 
now that i look closer

the tank pictured already has a regulator installed... the screw-looking thing protruding from the brass on top is where you would attach a handle. but you'd still need an adapter to fill baloons, and likely a pressure regulator... thise tanks can be at many hundreds of PSI and when you open the valve it is deafening.
 
There is no regulator on that tank. That's just the shut off valve thats missing a valve handle. You can see the square part that the valve handle would go on too and the top is threaded for a locknut for the handle. You could just use a wrench and very slowly open it and should be able to get a trickle out but I wouldn't recommend that.

You'll need a CGA 326 specific regulator such as this http://www.fishersci.com/ecomm/servlet/itemdetail?catalogId=-1&productId=2012962&distype=0&fromSearch=&storeId=10652&langId=-1

Regulators aren't cheap though for any high pressure tanks. expect to pay like 300 bucks for a brand new one, could possibly find a used one for much cheaper.

Or find a CGA 326 nipple to thread on to that and then find a cheap needle valve and use that to throttle how much gas to come out.
