Size of O-rings on a Ball Lock Corny Keg

Just wondering if anyone knows what size all of the O-rings are for ball lock Corny Kegs.
I have just bought a couple of kegs and wanted to replace all of the O-rings, I see that you can buy the corny keg O-ring packs from the brew stores but thought it would be cheaper to buy them individually from elsewhere if I know the sizes.

Someone posted the orings (McMaster part-numbers) on the Homebrew Talk forum at:  http://www.homebrewtalk.com/f11/mcmaster-keg-o-ring-list-233086/

Amazing, thats exactly what I was looking for and Mcmaster was the place I was going to look first.

Thanks

This is great... 100's of o-rings for the price of one kit bought from the homebrew store.  Thanks DRB!!

FYI, I just ordered 50 of these seals from McMaster.  They seem a little too thin to me.  The ball lock does not fit snugly.  There's lots of wobble in it.  I don't trust these to have a positive seal.  They aren't as thick as the ones I removed.  I think if you have the correct size seals, the ball lock should be snug when you slide it over the seal.  They are also a tiny bit smaller in diameter than what was taken off, which was a perfect fit.  Here is what I ordered based on what the link recommended: 3/32 Fractional Width, Dash Number 111.

I bought this set from amazon and have not had issues with o-rings.
