O-Rings are typically called out by the inner diameter of the torus and the diameter of the round cross-section. Thus, for an AS568-010 size 70 shore A, Nitrile would be: 0.239 x 0.070 70 BN. O-Ring Sizing Guides. For standard sizes, aerospace standard AS568 and ISO 3601 for metric sizes are used to give the dimension and tolerance.
