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 has an opening through which is received the end of a locking mechanism. The locking mechanism end is interferingly engageable with the coupler engagement portions such that with the nut being received coaxially over the coupler 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 so engaged, the locking mechanism end is interferingly engaged with at least one of the coupler engagement portions delimiting the rotation of the nut relative to the connector.
