O-ring tables
Check whether a dimension is standardized, and find the closest standard size in inches or metric units across all common standards.
Enter the inner diameter and cord thickness. The search will immediately show whether your measurement meets a standard and list the closest standardized size.
Many of the dimensions requested (often in Zoll) are not included in any standard. This search will show you the closest available standard size. If you need a custom size, just ask.
Select the appropriate standard. Each table lists all inner diameters and cord thicknesses along with their corresponding designations.
Note: The example size is for reference only. We offer over 200,000 O-ring sizes, 30,000 of which are in stock. Can't find your size? Just send us an inquiry.
