Grainger has it as well as all the stainless pipe fittings to do it for about $12.00, minus the, orings and washers which you have to buy in bulk and the valve they don't sell.

I ordered what I thought was these pieces from McMaster Carr and the ones I recieved were flat sided. I did have some luck with the trusty dremel and grinding a groove that holds the O-rings in place. More Beer sells the stainless versions which work great.

I have used the non-groved brass version and got it to work, but my next order will definitely be these nuts instead of the medium pressure ones.

Wow... I like that groove. Pretty sweet but my keggles don't leak with just flat washers against the orings that press on the keggle wall. Come to think about it I don't have orings between the washer and nut on the inside or the washer and ball valve on the outside. Now I got myself wondering why mine don't leak.....
