O-Ring Tables
Check whether a dimension is standardized and find the nearest inch or metric standard size across all common standards.
Enter inner diameter and cord thickness. The search instantly shows whether your dimension matches a standard and names the nearest standardized size.
Many requested (often inch) dimensions are not part of any standard. This search names the nearest available standard size. If you need a special size, just request it.
Choose the right standard. Each table lists all inner diameters and cord thicknesses with the corresponding designations.
Note: the example size is for orientation only. Over 200,000 O-ring sizes are available, 30,000 of them from stock. Your size not listed? Write to us at info@nh-oring.de.
