ABSTRACT:
A seal for a shaft is provided having a pair of back-to-back seal members. The seal members each have at least one split therein, although the seal members are positioned against each other so that the splits are staggered. Alternatively, one seal member is aligned back-to-back with a backing ring in a similar manner. Ends adjacent each split are interlocked to the opposite seal member or the backing ring by a post and hole engagement means.
