With the dimensions of the ring, is the 2nd dimension the circumference or diameter of the rubber o-ring ?

The second figure is the thickness of the ring. Just remember, these figures are very approximate, for example, 3.1 is about 2.9/3.0 according to my Vernier calipers

Are the dimensions listed inside or outside diameters?

Dear customer, the above dimensions are measured according to the outer diameter

What are the inside and outside diameters of the largest rings?

The outer diameter of the gasket is 30mm as shown in the picture, and the inner diameter is 23.8mm 30*3.1 represent the outer diameter and wire diameter of the gasket respectively (the wire diameter is the thickness of the gasket)
