- Speed is related to the generated friction between the seal and the dynamic sealing surface and, therefore, affects the performance of the seal. Low speed will cause increased friction; high speeds will cause a breakdown in the oil film between the seal and the sealing surface, causing the seal to run dry.
- Pressure causes extrusion of the seal into the extrusion gap, which exists on the no-pressure side of the seal. The gap can be increased with a corresponding lowering of work pressure.
- Brittleness of the seal will result if the temperature is too low or if the temperature is too high.
- Higher temperature affects the viscosity of the sealing media, resulting in greater extrusion and increased friction, leading to a reduced seal life.
