o-ring design guide

O-rings are stationary against gland surfaces and slide against shaft surfaces. O-rings tend not to roll in normal operation because fluid

O-Ring Gland Fill %O-Ring Volume) / (Gland Volume) Gland volume vs. O-Ring volume. About 25% void space or 75% nominal fill. Need space in groove to allow for volume swell, thermal expansion, and increasing width due to squeeze. Narrower groove for sealing vacuum or gas. O-Ring can extrude into clearance gap or get squeezed in two directions.

In order for the O-Ring to fit snugly in the groove, it is desirable to circumferentially stretch the O-Ring slightly. The recommended amount of stretch S

The best o-rings are useless without the right groove design which becomes increasingly important the more demanding the application environment.
