O-RING GROOVE DESIGN. Designing the parts of an application where o-rings will be applied is broadly termed "o-ring groove design". In order to seal properly, the o-ring has to deform in the application by being compressed and stretched in any number of ways. The design of the groove where the o-ring sits plays a major role in how the o

OSCILLATING SEALS - The inner or outer member of the assembly moves in an arc relative to the other, rotating one of the members in relation to the O-Ring. Sealing can be complicated by the fact that the O-Ring can snake or bunch in the gland. The relative motion of the moving part to the fixed part tries to carry its O-Ring contact with it, distorting the rubber circumferentially.

Jun 10, · Once in a while, you'll get an o-ring that comes in near the large end of the tolerance range for dimensions, and hence volume. Put that in a groove designed for nominal size o-rings, and you can't close the joint, or you'll fracture something while trying. Mike Halloran. Pembroke Pines, FL, USA.

O’ring Groove Design. As important as the o’ring seal itself is the groove that the o’ring seats into. The groove must be designed to accommodate not just the o’ring size, but also its intended usage; be it dynamic or static operation, radial or axial loading, vacuum or high pressure.
