Abstract
A shaft seal includes an annular rigid seal case insertable into a cylindrical bore in a seal housing. The joint between the seal case and the bore is sealed by an annular resilient sleeve stretched over the outer surface of the case. The sleeve is initially formed as a thin flat annular elastomeric disk by a low cost molding or slicing operation. Installation of the sealing element on the seal case is accomplished by stretching the disk radially and then turning it angularly from a radial disk orientation to an axial sleeve configuration.
