ABSTRACT:
A tie back assembly that uses expansion for connection and sealing is disclosed. The male component does not have any wall portions removed to hold a resilient seal. A seal is an option as anchoring and sealing can be accomplished by the expansion alone. The pressure rating of the connection is not reduced by material removed to accommodate a seal. A variety of expansion techniques can be used and the expansion can be done in a single trip with the insertion of the tie back assembly into the receptacle or in a separate trip.
