ABSTRACT:
Disclosed is contractible conduit sealing connector that features an expanded sleeve made from a heat recoverable metallic material which when exposed to a sufficient amount of heat is able to contract and secure at least two conduits together while at the same time enabling an expandable material contained within a chamber of the sleeve to expand and engulf any electrical conductors and/or cables extending through the connector between the conduits and fill the chamber sufficiently to provide a barrier against the flow of vapor through the conduits.
