Does anybody know where you can source these? There are plenty of sites for replacing the o-rings for lids etc. but I can't seem to find anything for the o-rings within the disconnects themselves.
I found a discussion on a US thread that gave the following dimensions:
9/16" OD x 7/16" ID x 1/16"
The o-rings in disconnects tend to have straight edges. Is there an industry description for this type of o-ring?
Only ever seen repair kits for the inside of disconnects in the US and that's what I bought, but with disconnects so cheap now is it worth bothering?
I seem to lose those o-rings at awkward times so a few spare would be handy.
If you can confirm the exact size pretty sure you will find them here. I bought various orings for kegs & other non keg sizes from them in the past. You need a US registered card to use them though.

I posted this in another thread when THC started selling used cornies.

Part numbers are :
109S for gas and liquid dip tube (pack of 50)
111S for posts (pack of 50)
417S for the lid (pack of 2)
These are the red silicone o rings
Edit: oops re-read your post. I'd say you'll find the inner disconnect rings on that site too. (if you can sort between the thousands of sizes they have) ???
are they food grade?
Quoteare they food grade?
Yeah. I've used them for a while now, no complaints.
After a bit of research I found what I was looking for. The type I needed are square cut (or lathe-cut or tetraseal). They're the ones with flat edges as opposed to a cylindrical shape. Here is the one I went for:

The material type is buna-n which is food grade.
Great reference with all the different types/sizes of orings including links to Amazon & McMaster http://www.homebrewfinds.com/2010/12/bulk-keg-o-rings-at-mcmaster.html

They used lead pipes for a good while too with no complaints
Difference is unlike smoking its accumulative and so stunted growth in children a whole series of compromised brain and central nervous function in adults along with high blood pressure and compromised reproduction in both sexes, kidney function, muscle and joint pain are just some of only the main symptoms so yeah no complaints. In 50 years time fingers crossed we will have the same view of lead as we have about cigarettes today.
The reason I asked about food grade in the first instance is that some of those o rings come in from China and they are cured with peroxides not permitted in EU and like some of the nasties used in my industry, it's the accumulated cocktail not the individual ingredients that's the problem and we should all be cognitive of what we are doing in our brewing.
The alcohol will kill us first of course :P
