Size:Standards are specified by their ISO 3601 dash number. O-Ring size is defined by inside diameter and cross-section (width) and is listed in both fractional and decimal dimensions with tolerances. The standards range in I.D.’s from .74 mm to 658.88 mm and cross sections (widths) from 1.02 mm to 6.99 mm.

The standard sizes used by O-ring manufacturers in the United States are defined by Aerospace Standard AS568B, Aerospace Size Standard for O-rings. The sixth series includes 20 sizes for boss seals. The standard sizes are also used for most military specifications. Cross-sectional diameters range from 0.040 to 0.275 inch. Inside diameters

The metric sizes are based on the International Standard ISO 3601-1:2002. Metric O-ring measurements are grouped into two series: G and A. Each has a different application. The G series is used for general purpose applications, while the A series is for Aerospace applications. O-ring seal measurements are based on their diameters.
