ABSTRACT:
A heat recoverable article for sealing splices having substrates of disparate size. The heat recoverable article includes a first heat shrinkable sleeve having an adhesive which extends over at least part of its interior surface and a second heat shrinkable sleeve which overlaps an end of the first sleeve. The second sleeve begins to recover before the first sleeve and holds the first sleeve in place as recovery continues, eliminating milk off.
