Standard O-Ring Sizes and Dimensions (Continued)
NOTES: (1) “AN”, “MS”, and “NAS” information is for size cross-reference only. “AN”, “MS”, and “NAS” O-Rings require special compounds. APG O-Rings are available in a variety of
compounds.
(2) Actual dimensions for standard (AN) shrinkage materials only. These correspond to AS568A dimensions. O-Rings manufactured out of compounds with different shrinkage
rates (other than AN) will produce slightly different dimensions and tolerances.
