Abstract
A two-piece interlocked labyrinth seal device for providing a seal between a housing and a shaft formed of two ring members, specifically a rotor and stator, connected to each other by a plastically deforming unitizing element. The rotor further includes one or a series of protrusions and recesses for providing a tortuous passage for fluid travel within the seal device. The system can be used on rotating shafts, rotating bores or as a baffle and has improved oil retention and water exclusion properties.
