O-ring reference chart

The AS-568* Standard O-Rings Quick Reference Chart lists every AS-568 Standard size O-ring — listed in inches, with inside diameters (ID) from 1/32 to 26 in., outside diameters (OD) from 3/32 to 26½ in., and cross sections (widths) from 1/32 to 4 in. — for simplified reference and easy-to-order parts.

All sizes are listed in ascending ID in both fractional and decimal sizes. The O-Rings are available in six basic materials: Buna-N/nitrile, ethylene-propylene, silicone, Neoprene, fluorocarbon, and fluorosilicone.
