The O-ring Reference Chart below covers the AS568 O-Ring Sizes published by the Society of Automotive Engineers (S.A.E.), and includes the Extended Sizes in the 400 Series. The purpose of this chart is to specify the inside diameters, cross-sections, tolerances, and size identification codes (dash numbers) for O-rings used in sealing applications and for straight thread tube fitting boss gaskets.
