ABSTRACT:
A unitized seal uses two casings and two attached disks of sealing material to provide four total lines of sealing contact. The casings have interleaved, axially and radially overlapping walls, the inner two of which carry the sealing disks. Radial overlap between the sealing disks, which flex easily past one another as the casings are assembled together, prevents casing pull apart during shipping and handling.
