The dip tube o-rings on all of mine are the square "quattro" style that are supposed to seal easier. The round ones are supposed to work, but I am ordering the quattro ones through grainger today for my kegs.
The 111 rings are for the outside of the ball lock pins. Regular ones work fine.
The 417 gaskets aren't in the regular grainger catalog. They can get them but they are more expensive than McMaster Carr. My sales rep with Grainger tracked them down for me, but they were almost $2 each.
In addition, some people say that the dip tube o-rings can be different between ball lock keg brands. The tubes are slightly different size, but the difference doesn't seem to be great enough to go up or down a size on the o-rings.
I need to find the source for race track lid gaskets.
