DISS oxygen outlet adapter
 
Piecing together my oxygen setup and it's all come down to finding this adapter.

I got a 20 cu ft welding oxygen tank and this CGA-540 medical regulator from ebay.

I got the Williams Brewing stainless oxygen wand with attached 2 micron stone, and I'll be using 3/16" ID hose.

My only problem now is connecting the hose to the regulator. Being a medical regulator I've learned it's a DISS type outlet. I've found what I need Female DISS to 1/4" hose barb adapter but it's proven mighty difficult to get a hold of one.

Anyone dealt with this?

I just ordered some of these for the time being, and also spoke with the person on the phone at this place and ordered one (she was out of stock, but is ordering more) for a more permanent solution.

I am in the exact same boat! Got my tank from AirGas, regulator from Amazon. Didn't realize it didn't have the means to connect the hose...had never heard of DISS....just know that nothing at Lowe's works. :(

I've been driving all around medical suppliers in my town. No luck. Best so far http://www.dremed.com/ a veterinary supply company - about $15.

Did the cheap plastic one you reference above arrive? Does it fit and work? I saw these on another site but they were packs of 25 with lots of shipping.

I need 1/4" hose barb.

I got a fitting from the welding supply shop, where I got the O2 tanks from, that worked. Got it from the threaded fitting on the regulator to a 3/16" barb, in brass. Simply take the regulator (and hose you plan to use, or just use standard 3/16" Belvex) to AirGas (or your local supply store) and get them to provide you with the fitting. Mine was maybe $1.50 each, in BRASS. As in, will never break (like plastic can/will).

See picture I just took of one of my O2 regulators setup this way. BTW, I'm pretty sure this is a standard fitting type for gas welding. Which is why the supply store has them.

DISS= diameter index safety system. We use them in the medical field to make sure oxygen stays with oxygen and NOT the other medical gases that we use throughout the hospital (ie. CA, heliox, NO, etc). Each fitting has a different diameter so they won't fit in other outlets. I'm pretty sure I have a couple of the 1/4" to hose barb adapters laying around (aluminum is what we use with that regulator).

@stevescott – the plastic pieces arrived and they indeed fit and will get the job done until I can track down the metal piece. I ordered six pieces and paid about $15 shipped.

I called the local AirGas because I saw the metal piece I need on their website, but he didn't have it in stock and said it could take a couple of weeks to get it.

I called the welding shop where I get my tank fills and they didn't know what I was talking about and said I'd need to get a new regulator.

NO! I WANT to flow at 1 LPM!

So AirGas should at least be able to special order the piece, as well as the second link in my second post above.

If you need one (and want to pay the shipping) I can send you a couple. I have the green plastic (which should last a LONG time unless you abuse the crap out of it) or the aluminum ones that will fit if you remove the current DISS fitting.

I got my fittings from a welding supplier down in Milford (Maine Oxy) that had the fitting in stock, on hand, and they're open on Saturday's (8am-noon). If you care, the address is: 47 Sumner St, Milford, MA 01757.

Garyr I sent you a PM about this. Thanks! Meantime I guess I'll call in at Airgas again though I'm not worried about a plastic fitting breaking when I'm going to use it for 1 minute 6 times a year. I just want a fitting! Who knew it'd be such a headache?

The set up in Golddiggie's pic doesn't look like mine. Did you remove the supplied DISS completely or is there some other piece in there?

BTW having researched DISS I fully understand the safety reasons behind it. What I don't get is why finding one has to be such a huge PITA.Even the guy in the recommended medical supply store shook his head while audibly exhaling...

It was super-easy for me. Not sure why it's such a pain for you. Must be another difference between where you are and I am.

BTW, I plan to brew as close to the legal limit as possible each year. So that's about 16-20 batches, a year.
