We're looking for this, only softer and wider (which would change the OD).

 So...4"OD...only softer and wider (which would change the OD). Of course "wider" changes the OD!!!!

See. That's what I deal with every_single_day. Is it 4"OD or wider? Wider? How much? 1/8", 1/4", or half a mile?

Are you an Engineer? Did you graduate from Clemson University? (or as we call it around here Clem's Son).

 I see what I can find

They are available from a couple of places linked to earlier in the conversation, we're looking for a bulk source.

These guys claim this o-ring will help with sealing older kegs.
May be worth trying.

Also, Williams Brewing has a similar product. Read the descriptions for both; they use nearly the same information, but Kegworks is cheaper. (Of course shipping may be different for both, so price may equal out in the end; just do your due-diligence when shopping)

Any luck?  Or is this something you need to do on a work day?

Whoops...I forgot.

 Work day better...more resources

How about now?

I too have a keg with an imperfection around the lip that doesn't like to seal.  I typically apply generous keg lube and seal, test and repeat until it passes the star san leak test.  Mine has held pressure for weeks at a time, though I've only used it to hold sanitizer so far.

Just ordered a few of those O-rings, I'll report back when I get them.

If someone wants to drill down and dig, I'm sure these are the guys:

 I can't find anything other than the Buna-N like from McMaster-Carr. Nothing in silicone.

 I called one vendor that makes silicone insulators for my company. They can make all we want for a $32,000 tooling set up fee and a contracted 60,000/year. I told him to wait and I would get back to him on that.

 Don't call me, I'll call you.

The tiny url takes me to a page that asks for my zipcode - is that what you intended?

I looked through their catalog, and it's not clear to me what would be a good substitute.  The standard is 4" OD, and 0.25" thick.

How much for the 60k?

 I stopped @ the tooling charge.

Usually a quote like that equates to "we don't want to deal with it".

Yeah Tom, apparently it looks for resalers in your area for their products. Closest one to me is El Paso and that's an hour away. I'm not in need of any at this point, just trying to nail down a supplier where prices may be reasonable.

[tschmidlin]

I'm not even sure what product I'm looking for though

[beveragebob]

Me neither     I guess if I was in the market for more(I' bought 3 or 4 from Williams years ago), I'd take it to said O-Ring reseller and see if he could match it by actual physical characteristics. Looks like some of these HB shops got the info locked up real good being I'm sure they are making a tidy profit on them. 

[tschmidlin]

I might have to take a corny to one of the local suppliers some day, explain what I want, and see what they have.  If it's a walk-in kind of place.
