Abstract
A lockwireless, anti-rotation fitting for connection to a connector. The fitting includes a coupler having a series of circumferential engagement portions disposed about an outer peripheral surface, and a nut receivable coaxially over the outer peripheral surface of the coupler, and which is threadably engageable with the connector. The nut also has a series of complementary circumferential engagement portions disposed about at an inner peripheral surface. With the nut being received coaxially over the first outer peripheral surface of the coupler, the nut is threadably engageable with the connector urging the coupler into a sealing engagement with a sealing surface of the connector, and with the coupler being engaged with the connector sealing surface, the first and second engagement portions are interengaged to delimit the rotation of the nut relative to the connector.
