摘要：
A hydrodynamic shaft seal assembly and method of forming hydrodynamic grooves involves forming a spiraling open channel portion in the face of the seal element, and cutting a flex-enhancing portion extending from the open channel portion further into the seal element to enhance the flexibility of the seal without further enlarging the open channel portion.
