The connector is provided with a sleeve having a chamber therewithin containing an expandable material which upon heating the connector after is is secured to the conduits is able 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. |
