Cover assembly of expanded elastomeric tubing having frangible support core structures

摘要

A cover assembly includes an expanded elastomeric tube (12) supported in the expanded state by an internal frangible support core (14). The support core (14) possesses sufficient strength to resist contraction of the tube (12) but will break upon the addition of relatively little additional external force. Breakage of the core allows the tube to contract and securely cover and seal to the object to which the cover assembly is applied.
