How are large O-rings measured?
To find this measurement, lay your o-ring on a flat surface. Use a ruler to measure from one inner edge of the o-ring across to the inner edge. Depending on the size of your o-ring, the ID may be recorded in inches or millimeters. This will help determine how large of an opening your seal should have.
