Dan,
I think density is the wrong parameter to examine. The better material property to look up is the elastic modulus, also called young's modulus, which is a measure of stiffness. It is orders of magnitude higher for cork than for the rubber used in o rings.
The mouthpiece shoulder touches the outside of the barrel, or the mouthpiece tenon touches the inside surface of the barrel (but I think there is usually a small gap there). But unless you purposely pull out the mouthpiece slightly, there will be a rigid contact surface between the two.
And of course, if the barrel is pulled out for tuning, there will no longer be rigid contact between the barrel and top joint unless you put a tuning ring in there.
