O-Rings, the hydrodynamic fluid film formation is dependent on several paramaters such ae viscosity, velocity, pressure, hardness and form of sealing rings. It can be shown theoretically and by experiment that the thickness of the fluid film between the mating surfaces is also essentially dependent on the direction of motion relative to the direction of pressure acting on the seal. Thereby the nonlinear increasing of leakage with higher pressures can be explained. Leakage and friction under fluid film conditions is determined by a characteristic nondimensional number. Transition from fluid film to boundary conditions can be evaluated by means of a dimensionless equation when for different types of packings several constants are experimentally determined.
