Section IV – Static O-Ring Sealing

desirable to use an O-ring one size smaller than indicated in the design chart. The design stretch is so small in these large sizes, that the O-ring tends to sag out of the groove before it is assembled. Using the next smaller size simplifi es assembly, but requires a reduced gland depth to attain the proper squeeze.

The stretch and expansion of the inner diameter should be considered An inner diameter stretch as installed in a groove may not be more than 5-6% because more stretch will reduce and flatten the cross section and thus reduce the squeeze. The inner diameter expansion to reach the groove during assembly should not exceed 50%.
