The swivel inion is no longer manufactured, it was packaged with several popular Waterway pumps including some Power Defenders. We have a substitue available for the swivel which included lock nut 415-4060 and 2″ socket 417 2110. The substitute does not have the “swivel capacity” but does have the same size male thread and same size female slip.
The replacement union is available at http://www.waterwayparts.com
