ABSTRACT:
A coupling device that provides a liquid tight seal at the connection with a conduit with easy installation. The device comprises a tubular connector body, a compression nut, a first sealing ring, a second sealing ring, a ferrule, and a lock nut. The coupling device may be installed fully assembled and does not require disassembly of the packaged product before installation. In the connector body a radial ledge is formed within the tubular spaces between the first and second ends. The radial ledge of the connector body has at least one depression. The ferrule has a tubular body with a radial flange extending from a first end portion. At least one protrusion extends from the radial flange that corresponds to the depression on the tubular body. When the depression of the tubular body engages the protrusion of the ferrule, it restricts the ferrule from relative rotation. This restriction allows that the coupling device be installed fully assembled.
