Does anyone know what the outside diameter of these tubes are. I am trying to match up some coneheads to fit them.

as I remember 2,2mm it is why only their own cones fit them.

2.2mm is correct!

And...

Microtube is the same diameter
Nanotube is the same diameter
Classic (extruded) medium is the same diameter

Our cones are the only ones that fit is one way to think of it...The other is that the tube has been designed based on necessity of I.D. wall thickness, material and the O.D. happened to be what it is so that we have super durable tubes that don't break.
