Abstract

A retrofit fitting for an externally threaded male nut that carries a face seal. The fitting is an adaptor with an internal thread to be threaded onto the male nut and an external thread to receive a female nut. The fitting carries a plurality of blades that engage matching blades on a cage engaged by the female nut. The cage is compressed against a head that bears the face seal by the female nut, so that relative rotation between the heads and face seals is prevented.
