Perma-Seal Self Aligning Connector

A metal to metal CT BHA seal without rotation.

The DTI Permaseal Self Aligning Connector enables connection and disconnection of the CT tool string at surface where rotation of the tool string is not possible. It is useful when making up long CT strings as part of a deployment system or running CT completions. The tapered nose of the upper connector provides efficient alignment with the lower portion. Once fully located, outer threaded collars make up the connection, providing a fully sealed joint that has high tensile and torsional strength.
