ABSTRACT:
A cable re-entry assembly for feedthroughs and the like is provided. The preferred embodiment includes an expansion mandrel positionally secured on the conduit with a heat shrinkable locking ring, a transition boot with a heat shrinkable sleeve portion and a rigid body portion which couples to a feedthrough nut, and a sealant between the conduit and the sleeve. Upon re-entry and re-use of the assembly, the mandrel mechanically expands the sleeve, when the sleeve is re-heated above its crystalline transition temperature, the expansion mandrel is translated against the sleeve and both the conduit and expansion mandrel are withdrawn from the sleeve. Following repair, the conduit is reinserted into the dimensionally unstable sleeve which is then heated to shrink about and reseal the conduit.
