A threaded pipe connection is shown which features a cylindrical metal-to-metal containment seal. In addition to the cylindrical sealing surfaces, the connection utilizes a separate ramp or ramp regions that simulate a pin swaging or a box expansion which results in the ability of the cylindrical components of the seal to assemble without interference or with only slight interference.
